Usa today reports that about 25% of all prison parolees become repeat offenders. alice is a social worker whose job is to counsel people on parole. let us say success means a person does not become a repeat offender. alice has been given a group of four parolees. (a) find the probability p(r) of r successes ranging from 0 to 4. (round your answers to three decimal places.)

P(x = 0) = 0.004

P(x = 0) = 0.047

P(x = 0) = 0.211

P(x = 0) = 0.422

P(x = 0) = 0.316

Step-by-step explanation:

We are given the following information:

We treat a person who does not become a repeat offender as a success.

P(Success) = P(person who does not become a repeat offender) = 0.75

Then the number of people follows a binomial distribution, where

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to evaluate:
