1. A club has 21 members, four of whom are executives. Five members are randomly selected to take part in a survey. a) What is the probability that four non-executive members are chosen? b) What is the expected number of non-executive members?(four marks)2. State which type of distribution (uniform, binomial, hypergeometric, none of these) would model each situation. (six marks) a) Drawing eight names out of a hat without replacement and recording the number of females. b) Generating random numbers between 1 and 100 and recording the number of prime numbers in 20 trials. c) Selecting the winning ticket in a raffle. d) Noting the wait time before you reach the front of a line. e) Recording the number of doubles when rolling two standard dice. f) Recording when the first occurrence of a red jelly bean occurs while selecting jelly beans from a bag.3.

Why? b) Rewrite the situation to convert it to a hypergeometric or binomial distribution, as appropriate.4. A total of 5000 tickets were sold for a raffle. The prizes are $1000, $500, $200, and $100.

The Panthers get 5 balls, the Wolves get 4 balls, the Kings get 3 balls, the Blues get 2 balls, and the Ducks get 1 ball. a) One ball is drawn to determine which team gets the first pick. Show the probability distribution for each team getting the first pick. b) To determine which team gets the second pick, all the remaining balls of the team that got the first pick are removed, and another ball is picked. What is the probability that the Kings get the first pick and the Panthers get the second pick? c) This process continues until all five picks are made. What is the probability that the teams get their picks in the order written above? d) What is the probability that the Wolves get the second pick? (five marks)6.
