Exercise 5(SOA). A car dealership sells 0,1, or 2 cars on any day. When selling a car, the dealer also tries to persuade the customer to buy an extended warranty for the car. Let X denote the number of luxury cars sold in any given day and let y denote the number of extended warranties sold. We have: 1 12 P(X = 0, = 0) = 5; P(X = 1, Y = 0) = 12, P(X = 2, Y =...
