E(X) = 19 and E(Y)=16 so Bob earns 3 dollars every time they play the game.

They both have equal chance of getting their number each roll (1/6), but every roll, Bob has all the high numbers to get to add to his sum total.

Bob can get 1, 3, 4, 5 and 6. Nick gets 1, 2, 3, 4 and 6.

Bob rolls a die and continues to roll until he gets a 2. He keeps track of all the outcomes of the rolls. He calls the sum of the outcomes of the rolls X. Nick does the same thing as Bob, only he keeps rolling until he gets a 5 and he calls the sum of the outcomes of his rolls Y. At the end of the game, Bob pays Nick Y dollars and Nick pays Bob X dollars. Does one of the boys have an advantage over the other? Which one?]]>2007-10-26T21:48:55Zhttp://www.mathisfunforum.com/viewtopic.php?pid=81342#p81342
