Let x denote the number of the 12 new credit card holders who will eventually default. Then x is a binomial random variable with n = 12 and p = .08. a. P(exactly 3 will default) = P(x = 3) = b. P(exactly 1 will default) = P(x = 1)= c. P(none will default) = P(x = 0) = Let x denote the number of defective motors in a random sample of 20. ................
