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 probability mass function of X and Y is given below: X Y 0 1 2 0 0.10 0.04 0.02 1 0.08 0.20 0.06 2 0.06 0.14 0.30 a. Find the marginal probability mass function of X and Y b. Give the verbal description the event (X≠0 and Y≠0) and compute the probability of this event
