USA Today reported that approximately 25% of all state prison inmates released on parole become repeat offenders while on parole. Suppose the parole board is examining five prisoners up for parole. Let x = number of prisoners out of five on parole who become repeat offenders. x 0 1 2 3 4 5 P(x) 0.229 0.360 0.224 0.169 0.017 0.001   a) Find the probability that one or more of the five parolees will be repeat offenders. (Round your answer to three decimal places.)   b) Compute ?, the expected number of repeat offenders out of five. (Round your answer to three decimal places.) ? =  prisoners c) Compute ?, the standard deviation of the number of repeat offenders out of five. (Round your answer to two decimal places.) ? =  prisoners
