hmm, I don't really see where the probability of 50% comes from? even if we assume that we don't have any contextual knowledge about what amounts would typically be carried in wallets, the probability of winning would surely have to depend in some way on the amount currently in my wallet? in the extreme case, if I had zero cash, my probability of winning (not just drawing) would be zero, since we can't carry negative amounts of cash.
- stefs 4y agowait - if you had zero cash in your wallet, you'd _never lose_, because you couldn't receive less.
- t_mann 4y agoYou'd never win, because you can't have more than the other guy. A draw is not winning
- zeroonetwothree 4y agoYou win if you have less
- t_mann 4y agoMy bad - then your probability of losing would be zero with zero cash, yes. But we still don't have a proof for the constant probability of 0.5 for winning.
