In Texas, 30% of parolees from prison return to prison within 3 years. Suppose 15 prisoners are released from a Texas prison on parole. Assume that whether or not one prisoner returns to prison is independent of whether any of the others return to prison. Let the random variable X be the number of parolees out of 15 that return to prison within 3 years. What is the probability that more than 5 parolees out of 15 that return to prison within 3 years?

The probability that more than 5 parolees out of 15 that return to prison within 3 years is 0.2784.

Step-by-step explanation:

The random variable X be the number of parolees that return to prison within 3 years.

The probability of occurrence of the random variable X is, p = 0.30.

A random sample of n = 15 prisoner are selected.

It is assumed that whether or not one prisoner returns to prison is independent of whether any of the others return to prison.

The random variable X follows a binomial distribution with parameters n = 15 and p = 0.30.

Compute the probability that more than 5 parolees out of 15 that return to prison within 3 years as follows:

Thus, the probability that more than 5 parolees out of 15 that return to prison within 3 years is 0.2784.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
