标 题: 面试题, make decision for two closed envelopes
发信站: BBS 未名空间站 (Thu Oct 3 13:00:22 2013, 美东)
An interview question:
Given two closed same envelopes, one may have $20 or $10, another one may
have $20 or $5.
You pick up one randomly and find it has $10, now you are given a chance to
make decision about whether to open another envelope.
If yes, you have to accept the money in it no matter it is more or less than
your $10 currently in your hand.
How to make the decision ?
Any help would be appreciated.
Thanks !
