Suppose that there are four buses carrying 148 students to a math competition. The buses carry 40, 33, 25, and 50 students, respectively. Let X denote the number of students on the bus of a randomly chosen student. One of the 4 bus drivers is also randomly selected. Let Y denote the number of students on the bus driven by that driver. Compute the expected values E[X] and E[Y ].
