Hmmmmmmmmmmm, ya.

Let's calculate the probability of the no-way-out, which is different
before and after the above situation happens. So, a similar case to the 
"car" problem happens.

The reason: the conditions have been changed.

Probably because there arn't many female audiences in scc.  I, as a male,
certainly don't feel much interested in handsome guys:-)

1/3 before seeing door 3, but 1/2 after seeing it.

The event (seeing a goat in door 3) is independent to the car is in door
1 or door 2, so conditional probability dosen't apply.  Or P(A|B) = P(A).

I have to remind you that the question is asked after the door 3 is

Maybe it could be one of the other programs you`ve been running on your system.

  Assuming the unit is in volume.
  No matter what you do, as long as the volumes in the two buckets
  remain unchanged, there would be always the same amount of liquid
  exchanged.  x amount of A MUST be replaced with x amount of B.
  Do we need a mathematical proof?

A friend of mine that works here at Bucknell University in central

research work. He is therefore currently casting about for leads on
employment. Last year his wife and two daughters were successful in leaving
China. My family and I helped to bring the reunited family to our town and
have been close ever since.

My belief is that Ji Qing Zhen's best hope for employment would be
something technical (since he has a Masters Degree in Mechanical
Engineering) in the trading industry. He is completely bi-lingual.

Any ideas?

I don't know if this is hoax or not, since it looks so easy.

    From: uphhswh@Msu.oscs.montana.edu
    
    this is one of the 6 problems in the final contest of national math contest of
    1986.
    a plane is filled with any way by either black or white points. Prove that:

I interprete this as "if you pick any point on the plane, it is either black
or white.

    there must exist one equi-lateral triangle whose 3 vertex are same color.
    
Here is the proof by reductio ad absurdum: assume there is no equi-lateral
triangle with 3 vertex of the same color (ELTVSC) on the plane.  There must be
at least two W points on the plane, not on the edges of the plane (otherwise
you can find an ELTVSC easily, you prove it).  Make two circles with the line
between the two W points as the redius.  All points on the two circles must be
B points excluding the two cernters if the initial assumption is true.  Since
the two W center points are not on the edges of the plane, you can make an
ELTVSC by selecting 3 B points on the two circles (you prove it).  Thus the
intial assumtion is untrue.  QED.

    I dont think there was more than 10 contestants that worked it out (judging by
    average sores and that it is the last one of 6 problem.)  I dont know the
    answer, which is why I didnt choose math as my career.

They probably got burned on the 5 problems came first.

     Same thing can be said about Vietnamese culture.  They have been heavily
influenced by Western culture, especially from French culture.  However, they
still have something in common with Chinese culture.  So if people keep 
arguing that Taiwanese are Chinese, the question can become "Are Vietnamese
Chinese then?".  This can be extended to Korean and Japanese cultures, they 
still use Chinese characters, so they Chinese too?

I think the solution is wrong.

If I have, say, 1000 doors. Only 1 car behind 1 of them. 
Then I take one door. Before I open it, the host open 998 other doors,
and nothing behind those 998 doors.
Then according to your opinion, the car will be 999/1000 chance behind
the other door kept unopened. and only 1/1000 behind the door I choose.

I think the way to explain it is:
1. When I got the right door. The host has 999 ways to select which
   door he left.
2. When I got the wrong door. The host has only 1 way to select which
   door he left.
So, the possibility for stick and win
   P(stick)= 1/1000*999*1 + 999/1000*0=999/1000
    the possibility for change and win
   P(change)= 999/1000*1 + 1/1000*999*0 =999/1000
Those two possibility are EQUAL.

Subject: The answer to the 13 balls problem
Organization: Educational Computing Network
Date: Sat, 19 Dec 1992 07:34:36 GMT

Guess I'm near the answer for the finding out the odd ball of 13 balls,
if there IS an answer. Or at least not far from the answer.
Divide the balls into 3 groups, as 4, 4, and 5, and call the group A, B,
C respectively.
Weight A and B, of course there are 2 possibilities.
1) A = B, then the odd ball is in C.
   Pick up 3 balls from A+B and weight them with any 3 balls from C.
   Again 2 possibilities.
   a) Balanced scale. Then the odd ball should be in the remaining 2
      balls of C. Pick any 1 ball from the other 11 balls and weight it
      with any 1 ball of the remaining 2 balls of C. If it is a balanced
      scale, then the last one is the odd ball. If it is not, then the 
      picked up ball from C is the odd ball.
   b) Not a balanced one. In this case you can find out whether the odd
      ball is a heavy or a light one. weight 1 in each side of the scale
      from the 3 balls of C. If the scale is balanced, then the
      remaining one is the odd one. If it is not balanced, as we've
      known whether the odd ball is heavier or lighter, then we can know
      which one is the odd one.

2) A <> B
   We must remember which side is heavier.
   Then use 5 balls from C (They are all good one) against 3 from A plus
   2 from B on the scale. Two possibilities.
   a) Balanced one.
      Obviously the odd ball is in the remaining 3 balls (1 in A and 2
      in B, as we already used 3 in A and 2 in B to weight against 5 of
      C. Weight the 2 remaining balls from B. If balanced, the last in A
      is the one. Other wise, based on the result of the first scale, we
      are sure the odd ball is in group B. And we now know the odd ball
      is a heavy one or a light one, then we are know one is the 
      one between the last 2 balls.
    b) None balanced one.
       First, as the 5 balls from C are good one, we can be sure the odd
       ball is a heavy or a light one. The other side is 3 A and 2 B. We
       still call it as group A.
       The tricky part.
       During the 2 times of scaling, if both time the A is heavier
       or lighter than the other side, then it means the odd ball is
       among the 3 A balls. If the A is heavier in the first scale and 
       lighter in the 2nd time or vise versa, then the odd ball is among
       the 2 B balls. Again, use the principle described above, we can
       pinpoint the odd ball.
