Solution: In Exercise 5.3, we determined that the joint probability distribution of Y1
Chapter 5, Problem 5.73(choose chapter or problem)
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
