Reading Material 0 [I t} 13 Snacks 1 240 9|} 3!] I lit) ED 12 a. Using the data in the table consttuct an empirical discrete biyariate probability distribution for x = number of snack items and y = number of reading materials in a randomly selected customer purchase. What is the probability of a customer purchase consisting of one item of reading materials and two snack items? What is the probability of a customer purchasing one snack item only? Why is the probability for = i]. y = D} = t]? b. Show the marginal probability distribution for the number of snack items purchased. Compute the expected value and yanance c. What is the expected value and variance forthe number of reading materials purchased by a customer? d. Shovlr the probability distnbuijon for t = total number of items in a customer purchase. Compute its expected value and variance. e. Compute the covan'ance and correlation ooefcient between x and y.
