Question 1072471: 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) 0.207 0.367 0.227 0.162 0.036 0.001
(d) Compute μ, the expected number of repeat offenders out of five. (Round your answer to three decimal places.)
μ =
(e) Compute σ, the standard deviation of the number of repeat offenders out of five. (Round your answer to two decimal places.)
σ = prisoners
