翻了翻以前的帖子, 对于新的中国护照,有人说有book number, 有人说没有。
我问了国内的父母,在照片页右边(不是右上角,右上角是护照号)的确 有一排横着
的小数字, 共8未数。
记得有人以前什么时候(旧贴子)说过,这个就是passport book number.
不知对否?请好心人回复一下。谢过。

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 given up the $10 that you have earned and 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 !

都有打折啊,什么的,10刀以下就能淘到了。唉,好想收集一套啊。

您好,我现在正在给我母亲填DS160表格, 也遇到了和您一样的问题
昨天在版上问了, 但是没有人回复我
所以来考古, 看到了您的帖子,
请问您现在确认了这个passport book number 了吗
您所描述的是否就是passport book number?
谢谢了!

what is the trick?
In my opinion,it's fairly simple, given $10 in hand, if open the other
envelope, you have 50% chance to gain $10 and 50% chance to lose $5, if you
trade stocks, you know the risk and reward,why it is so hard to make
decision?

置顶的签证常见问题里说不是这个number,我最后也没填。我估计不是什么大不了的事
儿,有护照号就足够了。仅供参考。

if you take action, you end up with either $20 or $5. 50/50
if no action taken, you end up with $10.
Risk&reward is straightforward. You may wanna consider the other factors to
make the final call.
Just for your reference and I might be wrong.

50%x5=2.5, 50%x20=10, the expected return will be 12.5 which is greater tan
10. So you give a try. Am I right? :)

Or you can say since the returns do not have a big difference, you prefer to
keep the 10. Since the 12.5 still has uncertainty and possible will get 5.
That part is analysis after calculation. :)
