10 Potentially Catastrophic Mistakes During Bank Robberies
by Tony Brissette
Most bank employees will never experience a bank robbery. But those who do

Suppose you pick a drawer without opening it, then I opened one of the

$20? |

My mother was a high priestess, my father I knew not. The brothers of my
father loved the hills. My city is Azupiranu, which is situated on the banks
of the Euphrates. My high priestess mother conceived me, in secret she bore

cast me into the river which rose over me. The river bore me up and carried
me to Akki, the drawer of water. Akki, the drawer of water, took me as his
son and reared me. Akki, the draw... 阅读全帖 |

发帖数: 141 | 49 This is an interview question of probability. The interview has been done.
In a room, there are 8 drawers in a desk, a man put a letter into one of
them with 50% randomly. After that, you enter the room, if drawers from 1 to
7 have been opened to show they are empty, what is probability of the 8th
drawer has a letter ?
My idea:
this is a conditional probability question and can be solved by Bayes
formula.
But, I got result 14/29 different from interviewer's answer.
Any help will be appreciated.
