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 4 (†) (2) (3 (3) where yı and 1 y2 are integers, 0 ≤ y ≤ 3,0 ≤ y ≤ 3, and 1 ≤ ₁ + y₂ ≤ 3. Find Cov(Y₁, Y2). Reference P(y₁, y2) = 2 - Y₁ - 12 Of nine executives in a business firm, four are married, three have never married, and two are divorced. Three of the executives are to be selected for promotion. Let Y₁ denote the number of married executives and Y₂ denote the number of never-married executives among the three selected for promotion. Assuming that the three are randomly selected from the nine available, find the joint probability function of Y₁ and Y₂.
