59% of all violent felons in the prison system are repeat offenders. If 34 violent felons are randomly selected, find the probability that a. Exactly 19 of them are repeat offenders. b. At most 20 of them are repeat offenders. c. At least 21 of them are repeat offenders. d. Between 15 and 19 (including 15 and 19) of them are repeat offenders.

Step 1
Probability that exactly 9 of them are repeat offenders: We can use the binomial probability formula for this: P(X=9) = (n choose x) * p^x * (1-p)^(n-x), where n=34 (total number of felons selected), x=9 (number of repeat offenders), and p=599/1000 (probability of Show more…
