This is not the Two Envelopes Problem that I am familiar with, but still a good one overall. Say you have an adversary. The adversary has two envelopes and in each envelop writes a number. It can be any kind of number as long as its real. You get to open on of the envelopes and see the number that is written, and then you must guess if the other envelope contains a number larger or smaller than the one you opened. Is there any strategy that you can employ to raise your probability of winning to better than half? Think about the answer for a while and then click the link above to see his solution.
