0 David_Walker Posted March 25, 2013 Report Share Posted March 25, 2013 (edited) Unless they both start with zero (which would make the game pointless), in which case that both A and B would always have the same amount, then whoever takes the 100th turn will have the most, as they'll have 50% of their opponent's points plus the points they already had. As B has the 100th turn (which is in the 14th set of turns taken between the two of them), B will have the most points at the end of turn 100.

0 jhawk Posted March 25, 2013 Report Share Posted March 25, 2013 (edited) After 91 games, A will hace won 13 in a row (1+2+..+13=91) and B will be virtually penniless. Howevere, B wins the next 9 games, decreasing A's stack to 1/2^9, leaving A now virtually broke. Assuming both started with equal money But david walker has easier solution Edited March 25, 2013 by jhawk Quote Link to comment Share on other sites More sharing options...

0 wolfgang Posted March 25, 2013 Report Share Posted March 25, 2013 B will win with 51 to 49 Quote Link to comment Share on other sites More sharing options...
0 TimeSpaceLightForce Posted March 26, 2013 Report Share Posted March 26, 2013 (edited) Without cognitive bias called "Gambler's fallacies" 3 : 2 in favor of A chances is presumable in the future..it is unlikely to happen for 6 consecutive win for B . Why is it that in NBA no team has ever recovered and win from 3:1 deficit in the finals Edited March 26, 2013 by TimeSpaceLightForce Quote Link to comment Share on other sites More sharing options...
