Question: Suppose that a die is loaded so that each of the numbers 1, 2, 3, 4, 5, and 6 has a different probability of appearing

Suppose that a die is loaded so that each of the numbers 1, 2, 3, 4, 5, and 6 has a different probability of appearing when the die is rolled. For i = 1, . . . , 6, let pi denote the probability that the number i will be obtained, and suppose that p1 = 0.11, p2 = 0.30, p3 = 0.22, p4 = 0.05, p5 = 0.25, and p6 = 0.07. Suppose also that the die is to be rolled 40 times. Let X1 denote the number of rolls for which an even number appears, and let X2 denote the number of rolls for which either the number 1 or the number 3 appears. Find the value of Pr(X1 = 20 and X2 = 15).
