3. A service station has both self-service and full-service islands. On each island, there is asingle regular unleaded pump with two hoses. Let X denote the number of hoses beingused on the self-service island at a particulartime, and let Y denote the numberof hoseson the full-service island in use at that time. The joint pmf of X and Y appears in theaccompanyingtabulation. Which island is most preferred by the customers?P(x, y)12.10.04.02.0820.06.06.14.30
