ya i got it...
but provided when they open the cup to reveal the ball also need to be taken into consideration leh
1st to take sure 1/3 chance
2nd to take, is 50% chance provided 1st open and reveal wad ball he took
3rd to take, is 1/3 chance provided non of the balls are revealed yet
lokitay u r clearly wrong
I'm not using any calculations. i said i am basing on logic. My logic is wrong? then please tell me ur chimalogy.
is not dont reveal, its when do they reveal
you can take one and open immediately, or wait for 3 to take their pick then open altogether
lol going 2nd isnt better than going 1st....
u r assuming that by goin 2nd, the 1st guy picks a black ball
I'm not assuming that he picks a black ball -_-" How can you say i assume he pick a black ball when i use %?
1st pick = 33.3% chance to pick the white ball but 66.6% chance to pick the black ball.
2nd Pick = 66.6% chance that 1st guy fail. Then you have a 50% chance of picking the white ball.
OMG. why am i repeating the same thjing over and over again ffs.
yep this is correct
but i dun understand y u then say that going 2nd is better ?
You really cannot understand, its ok. The fact that the SMU interview says nothing about going third speaks for itself?
LOL.
Anyway putting caculations aside. Just going by pure logic.
You pick first. Out of 3 Balls, you pick one. 33.3% chance to get the white ball
You pick second. You forgo the first 33.3% chance to pick. Which means you have a 66.6% chance that he will fail. And then out of 2 balls remain, you have a 50% chance of getting the white ball.
You pick Last. Your % is the same as the First. Bcos like how the first have 3 balls to choose, you have the last ball given to you. 33.3%
so in fact no one is in a better position. i could have by luck picked the black 1 , or by chance picked the white 1
the 3rd one could have done nothing all this while and handed a white ball upon revealing the cup
even tho its the same probability, it is still better to be the first to pick.
