1. An experiment was performed in which 2 dice were rolled a total of 4 times and the total roll was recorded each time. Complete the probability distribution for X where X is the discrete random variable representing the number of times the total roll was less than 4 or greater than 8.
2. Jason and Tina play a 7 game match of chess. The probability of Jason winning a single game is 0.4 while the probability of Tina winning a single game is 0.25. Complete the probability distribution for X where X is the discrete random variable representing the number of games that finished in a draw (tie).
3. A committee of 5 people must be selected from a group including 4 Russians, 7 Canadians, 2 Americans, 1 Mexican and 3 Columbians. Complete the probability distribution for X where X is the discrete random variable representing the number of Russians selected to the committee.
4. A basketball player makes 70% of her free throws. Complete the probability distribution for X where X is the discrete random variable representing the number of free throws she makes out of her next 8 attempts.
