You and your friend put your wallets on the table. The money is to be counted and whoever has more has to give it to the other. You reason that if you lose you’ll lose the money that you have in your wallet, but if you win then you know you’ll win more than that amount. Meaning, what you stand to gain is greater that what you stand to lose and since your chances of winning must be 50%, you figure you should play the game. But your friend thinks the same way. How can the game be to the advantage of both.
