So you say: "it is clear why BB, BG, GB, and GG have equal probability in the unrestricted case"

The restricted case is just the unrestricted case + one additional bit of information, that is, you're told that GG is not an option. This eliminates GG from the unrestricted case, but says nothing more about the probabilities of the other options. So the probabilities stay equal, although they now equal 1/3 each (if you eliminate options, the remaining options all become more likely).

What you're missing is this: The statement "the older child is a boy" has more information than the statement "one of the children is a boy". The first statement allows you to eliminate two options (GB and GG), while the second statement only allows you to eliminate one option (GG).

The "older" part is not fundamental to the problem. Equally, the statement "the taller child is a boy" has more information than "one of the children is a boy". The problem with this is that probabilities for height are not so friendly like the 50/50 probabilities for birth order (e.g., boys are likely to be taller than girls, older children are taller than younger, etc), which introduces unnecessary complexities to a logic problem. So that's why birth order is used for these types of puzzles.

I'm just sick of stuff like this.

An employer is expecting that an employee is loyal,
but nevertheless he's trying to noble the potential
employee from the beginning.

But you would be dumb doing it the other way, right?
Sorry, but this kind of smartness harms the whole
society.

So all the humble and self-doubting people are getting
less than the loud and playing ones. Sure, the loud
ones are the better, more loyal employees, right?

But you have to learn to be louder! No I don't have to
and I don't want, because I like it the way I am.
What about this:

I have two teenagers. One is a boy of 13.

Do we encounter a similar situation with regard to the odds of the second teenager being a boy?

edit: I'm thinking the odds are exactly the same, 13/27, by coincidence, as there are seven possible teen ages.

So then, what about this: One is a boy named George. Or One wears a black shirt. Or One likes chocolate.

Doesn't this mean that the more information we gain about the boy, the less likely it makes it that his sibling is a brother?

When considering the case that the older son was the one born on a Tuesday, that gives 14/28 possibilities. One of those 14 is the case that both were born on Tuesday.

When considering the case that the younger son was the one born on a Tuesday, that gives 14/28 possibilities. One of those 14 is the case that both were born on a Tuesday.

But woops, we've already covered the case that both were born on a Tuesday in our first count. Removing the duplication gives the 13/27.

You then combine those two probabilities.

The 13 wasn't arrived at by excluding the possibility that the second child was a boy on Tuesday, it was arrived at by discounting the case that they were both born on Tuesday as it had already been covered in the previous sub-calculation.

They are independent, but you get information about both ("One of them is a boy."), therefore p=1/3.

If you say "the older is a boy" then you have a statement about one son and no information whatsoever about the younger one, therefore p=1/2.
No, you do not remove the duplication.

If you have two kids there are 4 possibilities, not 3: BG, BG, BB, GG

"One of them is a boy." is a completely different scenario and no one is arguing about it. (BG, GB, BB, GG - by saying one is a boy you exclude GG leaving 1/3.)

In this case we are asking if the other is a boy NOT if the other was born on Tuesday.

There are 14 possible permutations for a child

Mon-Sun Girl

Mon-Sun Boy

which for two children gives a total of 28:

Child 1 is Boy, born Mon-Sun

Child 1 is Girl, born Mon-Sun

Child 2 is Boy, born Mon-Sun

Child 2 is Girl, born Mon-Sun

Note that we haven't said which child is 1 and which is 2, and in fact we don't know because we haven't been told - this is the important bit.

So, for our unknown child to be a boy, it must be one of the following 14 permutations:

unknown child is Child 1, boy, born Mon-Sun

unknown child is Child 2, boy, born Mon-Sun

but one of those permutations is already taken by our known Tuesday boy, so we have to remove one of the Tuesday permutations leaving 13 possible outcomes out of 27. Note that one of those 13 outcomes is 'unknown child is son born on Tuesday' - it's perfectly valid to have both sons born on a Tuesday.

Note also that we can't say which permutation we're removing until we know which is Child 1 and which is Child 2, just that one of them is taken.

If the original statement were phrased as '... the older child is a son born on a Tuesday' then you would have a constraint on which was Child 1 and which was Child 2 and then the probability would be 1/2 as expected because you would know up front that you were entirely discounting, say, Child 1, AND that the removed Tuesday permutation also belonged to Child 1.

But I stand to be corrected!

First, saying Mon-Sun is confusing almost everyone since most people start the week on Sun, not Mon. (Even in Europe Christians start the week on Sunday.)

In any case, as I replied here http://news.ycombinator.com/item?id=3290118 you can not remove the duplication! It's two different situations, even though they may appear the same.
A professor of mine one asked the class: "How would you like to live your life 10% better?" Everyone was like "yeah, of course"

The professor's friend would always ask for discounts, everywhere he went. He would normally get a discount of about 10%. This was simply because he asked. His theory was that if he could get a discount, why not ask? It doesn't hurt anyone and you just have to get past the social stigma of "haggling."

So the professor's challenge for us until next class was to ask for a discount, or more simply "is that your best price?"

Some of the results:

A friend of mine got a free appetizer at a restaurant he frequents

At least 3 people found out that Taco Bell has a student discount program

One person used this in his salary negotiation (literally "is that your best offer?") and instantly got a 5K bump. He was going to take the job anyway, but got $5k more without any hassle.
ANYONE WHO SAYS THE ANSWER IS OTHER THAN 1/2:

Let's simplify the question:

If a man says "I have two children, one was born on a Tuesday," what is the probability that they are both born on a Tuesday?

Is the answer to this 0 or 1/7 in your opinion? (Or something different).
I've been thinking about this for an hour, and I'm now convinced that the author is wrong. The fact that we found out about one of the children from the father means that all probabilities are not equal, even though they're treated here like they are.

The difference is between the information being offered, and determined independantly. I'll do this with the boy/girl problem, for simplicities sake.

If we ask a man if he has at least one boy, and he says yes, we can work out the chance the other child is a boy like so:

Assume all four possibilities are equally likely:

BB
BG
GB
GG

If we ask him if he has at least one boy, and he says yes, we effectively filter off GG, which brings the list down to:

BB
BG
GB

Therefore, the chance of the other child being a boy is 1/3. Pretty straight forward.

However! Because the father offered the information on his own, it effectively turns it into the author's other problem, where the older child is a boy, find out the gender of the younger child.

The trick is that he's equally likely to give information about either of his children, therefore there are eight possibilities:

He gives information about child A:

BB - B
BG - B
GB - G
GG - G

He gives information about child B:

BB - B
BG - G
GB - B
GG - G

There are still 3 possibilities, but BB is twice as likely as the others, because if both children are a boy he's definitely going to reveal the gender of one of them as a boy; whereas if one is a girl and one is a boy, there's only a 50% chance he will.

BB - 50%
GB - 25%
BG - 25%

So, the answer to this:

You meet a man on the street and he says, “I have two children and one is a son born on a Tuesday.” What is the probability that the other child is also a son?

Is 1/2

The answer to this:

A man has two children, and one is a son born on a Tuesday. What is the probability that the other child is also a son?

Is 13/27

It's nitpicky, but I think the author should be very exact about this kind of thing, since he's trying to clear things up.

Sounds like one of the upsides of working at a place where I work now, where there is a salary scale.

Places that play these kinds of games with salary really annoy me. For my first post-college job, as a DBA, I was offered $29,000/year (this was in 2000). I knew they had just lost key people and had a bad reputation for compensation, so I laughed and walked out of the room.

In the parking lot, we agreed to $65k + stock. Most of my colleagues didn't bother, and got stuck with lousy pay for a couple of years.

Often you still use units of % change relative to the initial quantity, though I suppose you could define it either way. For example, if we're comparing a country with an inflation rate of 4% and one with an inflation of 8%, we might say that the difference between the rates is 4%, in that |rate1-rate2| = 0.04, as opposed to measuring one in terms of percent of the other.

How to deal with robots and get your poodle a job (On handling recruiters)
We've had people say that. Just letting you know, we don't hire people who say things like that.

You can decline to say, that's fine, but don't feed us a line of bullshit.
HR's job is to hire someone at the very least amount possible. They have a range to go by with and at quite a few companies, the difference between upper salary limit of the position that was budgeted and the salary that the hire was made either goes into a pool that is split between the HR recruiters at the end of the year or they get a certain %age of the amount as bonus.

Always do your research on similar positions at the same company or different companies through a site like glassdoor.com before even negotiating. You should not be going in blind. Also do research on how much people are making at a role that is similar to yours in terms of work / title / experience. Remember that if there are 2 same positions at a company or even in a department or a team, difference between their salaries could be big.

If you're asked to divulge salary history, don't tip your hand. I've made this mistake a couple of times and I have regretted it / having had to settle for a lower salary. If insist on you giving them a number, quote a number that's 10-15% higher than your annual salary (Have to be careful of the company not finding out your current salary through some other means).

Always tell them about the value you bring to their organization and your experience and that you deserve this much $ amount because of how much the future company will benefit from your skills. Talk about positive recommendations & performance reviews, performance bonuses, awards & accolades you've earned at your current/ past jobs or at school. Do not bring in a comparative number (this company is offering me this much) unless you really need to as it sort of casts a negative impression about you being all about money. Potray how highly you're interested in the position but you feel that the offer is on a conservative side as far as the market rate goes.

If they cannot offer a higher $$$ figure, and you really like the profile, you can negotiate better benefits like full health coverage vs. partial, higher # of vacation days (some companies allow you to cash out some vacation days at the end of the year), commuter benefits, etc.

Just be confident and do not hesitate to ask for more (as long as it's realistic and comparable to the going rate). Also, rehearse the negotiation with a friend or just simulate the conversation in your mind before you actually do the talking with the hiring manager.

Disclaimer; Some of this might not be right. Please feel free to correct any erroneous statements I've made. :)
I'm so tired of the double standard.

If men are raised and "socialized" that they are the rightful leader of the family, and it's not only okay but right to hit their wives, we hold them personally responsible for their actions.

If women are raised and "socialized" not to negotiate, we blame society. Because… women aren't smart enough, or whole humans enough, to do anything but what they're told?

Ladies, take control of your own destiny, or be a victim of your own making. It's your choice.

This is just a little novelty item that will probably sell just fine. Like Chumby.
Okay. To respond to both of you - I have put this in programming just to check, and I think you are taking a different inference from the question than I am.

Under your inference, the man wouldnt have mentioned anything unless he had at least one male child. (in which case you can say the GG scenario is gone, but GB BG and BB are equally probable)

Under my inference, the man just told me the sex of one child at random.... (in which case BB is twice as probable as GB or BG - where he could have equally said 'i have at least one girl')

That sound reasonable to you? I have it in ruby form if you are interested :)

The blogpost linked to by someone above (http://blog.tanyakhovanova.com/?p=221) uses this explanation, which is very different (to me) than the one in the main link, and I can see why this gets to 1/3:

"A father of two children is picked at random. If he has two daughters he is sent home and another one picked at random until a father is found who has at least one son."
Sorry, I should have said a higher proportion of two-boy families, not a higher proportion of boys. 13/27 is more than 1/3, which is the proportion of two-boy families before you eliminate the families without tuesday boys.
