Title: Two-face bomb
Post by stardust496 on Dec 28^th, 2008, 6:05pm

So I am struggling with the two-face bomb problem

http://www.ocf.berkeley.edu/~wwu/riddles/hard.shtml#2faceBomb

I don't have much of a probability intuition so am kind of lost where to begin. Any hints ?

Thanks!!

:)

The threads about this problem are a bit old, so you have to remember to set the maximum age when searching for them.

There are ones here (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_hard;action=display;num=1033240646) and here (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_hard;action=display;num=1179807186).

If you want to begin on your own, begin with fewer than 2000 digits; like 4 or 10, then try to see if you can find an approach that scales up.
