3. You are playing a very simple gambling game with your friend: a $1 bet based on a roll of two sixsided dice. That is, you each bet $1 and roll the dice: if the outcome is even you win your friends $1, if the outcome is odd you lose and your friend takes your dollar. How is your risk different if you play this game 100 times in a row versus just betting $100 (instead of $1) on a roll of the dice?
