The exercisie is in the attachment. I am trying to solve it using a Binomial distribution, using n = 64, and p = 0.2. P(X=1) = (64) (0.2)^1 (0.8)^63 ( 1) and, I get that P(X=1) = 1.00434 * 10^-5 However, this does not seems correct, can anyone help me here?? I need to submit this in 4hours, so please help me. Thanks.
