Problem 5.73

In Exercise 5.3, we determined that the joint probability distribution of Y1, the number of married executives, and Y2, the number of never-married executives, is given by p(y1, y2) = 4 y1 3 y2 2 3 y1 y2 9 3 , where y1 and y2 are integers, 0 y1 3, 0 y2 3, and 1 y1 + y2 3. Find the expected number of married executives among the three selected for promotion. (See Exercise 5.21.) 5.74 R
