Answer by ilana(307)   (Show Source):
You can put this solution on YOUR website! You need to know the probability of rolling a double. When you roll two dice, there are 36 possible combinations because each die is 1 of 6 things. 6 of these rolls are doubles, each of the 6 possible pairs. So, you have a 6/36, or a 1/6 chance of rolling doubles. I would think that for a fair game, if you are expected to win 1 out of 6 times, you should get back the money you put in those 6 times. So you would pay $5.00/6 each game, or 83 cents. I am not, however, completely sure if this is the definition of "fair" you use in your class, so if this was not super helpful, I am terribly sorry.
