4. The random variable D counts the number of iterations of the process required to have a ◇ turn up for the fourth time. What are P(D = 4), E(D), and V(D)? 5. The random variable Xk, where k ≥ 1, counts the number times a or turns up in in the 100(k − 1) + 1st through the 100kth iterations of the process. The random variable Y returns n if Xn > 50, but Xk ≤ 50 for all k with 1 ≤ k < n. What are P(Y = 3), E(Y), and V(Y)?
