1. John has a choice between two options to play 3 tennis sets with his father ( F ) and Bill ( B ) atennis champion. He can either play in the order F-B-F or in the order B-F-B. Bill is a better playerthan his father. If John wins two sets in a row he will win a prize.(a) Which order should John choose? Why?(b) Let Z be the number of times John wins. If instead John wanted to maximize E[Z] shouldhe make a different choice? Why or why not?2. Suppose X is a binomial random variable with parameters n and p. (i.e. there are n trials). SupposeY is a binomial random variable with parameters n and q. Suppose also that 0 p or false?: P(X k) P(Y k) for any k. If true provide a proof. If not true provide acounterexample. (Hint: if you re having trouble simplify by considering small n.)
