| Dec 14, 2013 at 1:00 | comment | added | Sam Hopkins | @StevenLandsburg: imagine the dealer turns over the bottom card of the deck when you guess, instead of the top one. Clearly this situation is symmetric to the one described above, but also clearly every strategy gives 50/50 odds as the outcome is determined before the game even starts. | |
| Dec 14, 2013 at 0:32 | comment | added | Steven Landsburg | I see how to solve the card problem by proving a more general result for R red cards and B black cards, and then using induction on the size of the deck. (There are two cases: Either my strategy is to guess before the first card or my strategy is contingent on the first card.) But I wonder if that's the "very elegant way" you have in mind. | |
