Consider a person wanting to play a game of dice. Whenever he wins a game he gets 1 dollar from his opponent. If he looses he gives his opponent a dollar.
He starts by rolling the dice 4 times hoping to get at least one 6. After a number of tries he thinks that his chances would be better if he rolls two dice 24 times hoping to get at least two 6.
The question is: from where could he have gotten the idea of changing the number rolls (and dice) so as to improve his chances of winning some money?
