Unformatted text preview: b (3 ,p ). Thus, p 3 = 0 . 125 and p = 0 . 5. But Pr { N = 1 } = 0 . 5 6 = 3 . 5 . 5 2 . Hence, N is not a binomial random variable. Therefore, N is not in an ( a,b, 0) class since the class contains only Poisson, binomial, and negative binomial distributions. (b) The probability of Pr { S = 9 } = 0 . 25 Pr { M 1 + M 2 = 9 } + 0 . 125 Pr { M 1 + M 2 + M 3 = 9 } = 0 . 25 . 02 + 0 . 125 . 064 = 0 . 013. 1...
