1. The random variable H counts the number of ♡s that turn up in the first 12 iterations of the process. What are P(H = 4), E(H), and V(H)? 2. The random variable Z returns a number for the card drawn on the forty-first iteration of the process: 0 if it is a ♡, 1 if it is a ◊, 3 if it is a, and 4 if it is a What are P(1 ≤ Z ≤ 3), E(Z), and V(Z)? 3. The random variable W counts the number of iterations of the process required to have an ace (i.e. A♡, A◊, AS or A) turn up for the first time. What are P(W = 4), E(W), and V(W)?
