I. The 2/3 answer: INITIALLY, the probability is 1/3 for each of the doors, 
   the No. 1 got 1/3. Since the car is found not in No. 3, "so" the No. 2 has 
   a probabilty of 2/3=1-1/3. 
                         ^^^ from No. 1 based on the INITIAL calculation, a
                               self-centered approach.
                                        
II. The 1/2 answer: CALCULATE FROM THE NEW SITUATION. 

The conditional probabilty question has been changed, after the host did 
sth. UNWISE. I like the 1/2 better than 2/3, though the latter is larger.

This is a serious qeustion, not a joke. Just imagine,
Chairman Mao was born on 26 December! One day after
Jesus was born! Was it merely coincidence? Doubtful.
Although both of them are dead, they always live in 
people's hearts! Everywhere we see their pictures! Read their
instructions! Lots of songs and peoms are devoted to them!
Both of them are revered! When a SCC get exited, s/he would say:

I am seriously considering hanging one in my room.

So it's in everyone's interest to try and cooperate with each other.
ROC must take into account PRC's interest.  PRC must take into account
ROC's interest.

We know more or less, what the PRC's attitude toward ROC is.  Is the

As long as the "status quo" political situation remains, there
shouldn't be any problem.  My point is that changing the "status quo"
introduces a lot of risks.  Are they worth the benefits?

I'm not the one who is always complaining that others should listen to
the Taiwanese people.  I am trying very hard to sort out what people
in Taiwan think and to adjust my attitudes and arguments to take into
account the views of the Taiwan electorate.  Perhaps someday, the
Taiwan electorate will vote for ROT, and I will have to modify my
arguments and salvage some sort of Mainland/Taiwan union.  

That day has not arrived.

You, after preaching about how much the Taiwan electorate ought to be
listened to, seem blindly unaware of last December's election results.
ROC seems acceptable to most Taiwanese voters.  "Two Chinas" seems
acceptable to most Taiwanese voters.  Yet you seem to keep insisting
that "two Chinas" is an impossible option, and that "Taiwan cannot be
a part of China without becoming part of PRC" even though the
government which has been elected by Taiwanese voters seems to think
that it can.

Don't you see the contradiction?

This is the 3rd of the pretty girl who have had the previlege to be posted

bit more beautiful than Noriko in MISS.GIF, but not so cute. Over all, I
like Noriko better. What do you guys think?

Note: If any of you guys or gals wants to post pics too in SCC. Please
follow these two common sense rules:
1: Don't post any R-rated, X-rated or offensive stuff, we don't want SCC get 
sensored by some sites because of possible offensive material.
2: Please keep the volume down!!! I suggest no more than two or three pics
each day in SCC. Many sites don't have picture groups 'cos they take too
much bandwidth and have too much traffic. Our goal is to let as many people
enjoy SCC as possible. So I'll be very sorry if some site close down SCC
because of its traffic.

BTW, I wasn't smart enough to think of these rules, thanx to those guys who
reminded me of them. SCC is not a moderated group, so we have to do some
policing among ourselves.

Depends on what parts of America you are talking about.  It is kind of interesting

Then we go to war with China?  No No No, just kidding.  I don't think we need to
be worrying too much of that kind of scenario.  If China indeed become a economic
superpower, it would help the WEST also in their economic growth as well.  As more
nations throw away their political differences, global economic will tight to each
other closer than ever.  I just don't see how any kind of depression can only hurt
on big place and not other places?  Just look at the WEST at this moment, depression
is every where in all western countries.  China is growing because it is still a
third world nation.  Like I said before, "the Long March" is far from finish!

hi, every "math forest high hand", I check the problem again, here is the final
conclusion.

(1) my equation may have a "zeng gen", and if it has, it is y=1.
(2) y=1 is always a solution of my eqution.
(3) consider the ritio of derivative of LHS & RHS, it is (an+n)/(an+a)(1/y).
    It decreases monotonously from infinity to 0.
    So, besides y=1, there is one and only one other positive solution,
because, when y increases from 0, at first, LHS speed of increase is bigger
than that of RHS, then meet RHS, then RHS meet LHS.
(4) at intersection, the two derivative cannot be equal, since one was left
behind and is catching up with the other.
(5) so the final conclusion: if y=1 is also a solusion of original eqution,
which is equivalent with a=n, then there are TWO positive solusions of original
eqution;  if a is not equal to n, then there is ONE positive solution of
original equation.

have a good time in final week
