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 P(x) 0.209 0.368 0.229 0.172 0.021 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.) How does this number relate to the probability that none of the parolees will be repeat offenders? O These probabilities are the same. O These probabilities are not related to each other. This is five times the probability of no repeat offenders. This is the complement of the probability of no repeat offenders. O This is twice the probability of no repeat offenders. (b) Find the probability that two or more of the five parolees will be repeat offenders. (Round your answer to three decimal places.) (c) Find the probability that four or more of the five parolees will be repeat offenders. (Round your answer to three decimal places.) (d) Compute &, the expected number of repeat offenders out of five.
