The interviewer asked a question to all 8 of us, if you have a cup with 1 white ball and 2 black balls, and it is a competition. Person who picks the white ball wins. Would you go first or go second?

The rest all give very cock reason like i will share the winnings etc etc
I tried to be different from the rest and I answered "it dosent matter which, same chance of winning." when the interviewer asked why, i tell him gut feeling LOL. After i explain becase it dosent matter what colour ball the first person got, because there is only 1 white ball in total. After that i worked out the probability in front of everyone.

SAKTI a not??! Got chance they will accept me?

I did screw up the front part because i volunteered to go first and describe myself. Got nothing to say
wa lao... who also know any order also same chance... sec 2 question

You're assuming that the first person to hop in is guaranteed to lose.
No assumptions

If u go 2nd u have 50 50 chance
As opposed to 1/3 2/3 chance Ifu go first

Remember to distinguish between mathematical probability and real life probability.
