| May 15, 2013 at 19:49 | comment | added | Dag Oskar Madsen | It would be nice if this thought experiment with two players with symmetrically opposite strategies could be turned into a simple explanation why the EV of the ratio $G/(B+G)$ \emph{cannot} be $1/2$. I don't quite see how to do it, but it seems only one player can gain money, and the loser will sit longer at the table than the winner does. | |
| May 15, 2013 at 10:17 | comment | added | user112109 | @Steven Landsburg: DZ calculated the difference for 10 couples: 47.5 grils and 52.5 boys. Here comes my receipe for your gambling: Put everytime 1 million bucks on black. If black comes don't stand up but start your next series. During 10 series there will be less reds than blacks. It is really ridiculous that nobody ever thought about this simple method of making money! But what happens, if another player will bet on red everytime also always stopping a series, when red comes (not standing up then but starting the nexts series)? 52.5% red and simultaneously 52.5 % black? Overflow??? | |
