Let's say that we are making a table game at a casino whereby you pay
some amount x to roll one die. Whatever number the die lands on is the
amount
of dollars you win back. Now, say that you change the game a bit so that if
the player doesnt like his roll the first time, then he can reroll, in which
case it's as if he never rolled the first time. How much would you charge
now just to break
even?
