1. In a three-child family, MAKE a probability distribution chart to determine the expected number of girls.

1. Suppose you are designing a board game with a rule that players who land on a particular square must roll two dice to determine where they move next. Players move ahead five squares for a roll with a sum of 7 and three squares for a sum of 4 or 10. Players roll back "n" square for any other roll. Use a probability distribution chart to determine the expected number of moves based on these rules.

1. make rules for a game involving the sum of two dies that will result in an "expected" profit of $1 for the game operator. State the rules that the player must agree to and then make a distribution chart to show that the expected value is $1.
