Let X1, X2, X3, X4, X5, and X6 denote the numbers of blue, brown, green, orange, red, and yellow M&M candies, respectively, in a sample of size n. Then these Xi's have a multinomial distribution. Suppose it is claimed that the color proportions are p1 = 0.21, p2 = 0.13, p3 = 0.19, p4 = 0.2, p5 = 0.12, and p6 = 0.15. (a) If n = 12, what is the probability that there are exactly two M&Ms of each...
