(choose chapter or problem)

A service station has both self-service and full-service islands. On each island, there is a single regular unleaded pump with two hoses. Let X denote the number of hoses being used on the self-service island at a particular time, and let Y denote the number of hoses on the full-service island in use at that time. The joint pmf of X and Y appears in the accompanying tabulation. p(x, y) | 0 2 0 | .10 .04 .02 x 1 | .08 .20 .06 2 | .06 .14 .30 a. What is P(X 1 and Y 1)? b. Compute P(X 1 and Y 1). c. Give a word description of the event {X 0 and Y 0}, and compute the probability of this event. d. Compute the marginal pmf of X and of Y. Using pX(x), what is P(X 1)? e. Are X and Y independent rvs? Explain.
