4. Assume that the joint pmf of (X,Y) is 0.20 0.10 0.05 0.25 0.10 Find (1) a: (2) P(XYs1): (3) the marginal distributions. Mark
X = number of books Probability 1 0.05 2 0.10 3 0.20 4 0.35 5 0.10 6 0.15 7 0.05 13. For this problem, look at the "number of books" problem above. (a) Compute the expected value of X and interpret its meaning. Answer: E(X) = 4 (b) How many books are expected to be purchased if the enrollment is 20,000 students? Answer: Expected number of books = 4.20,000 = 80,000 (4.2.1)
