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 USE SALT (a) Find the probability P(r) of r successes ranging from 0 to 4. (Round your answers to three decimal places.) P(0) = P(1) = P(2) = P(3) = %3D P(4) = (b) Make a histogram for the probability distribution of part (a). 0.35 0.4 0.3 0.25 0.3- 0.2 P(r) P(r) 0.2 0.15 0.1 0.1 0.05 0 1 2 3 4 1 3 4 0.35 0.6- 0.3 0.5 0.25 0,4 0.2 P(r) P(r) 0.3 0.15 0.2 01 0.1- 0.05 1 2 3 4 2 3 4 (c) What is the expected number of parolees in Alice's group who will not be repeat offenders? parolees What is the standard deviation?

Saved Listen             Question 1 options: Nova has a pop quiz with 9 multiple choice questions. Each question has 3 answer options. Assume that Nova randomly guesses on every question. Find the probability that Nova passes the test with a score of 70% or more. Round to the nearest tenth of a percent (1 decimal place percent).       Question 2    Saved Listen             Question 2 options: The chance of an email being spam is 44%. If you receive 33 emails in a single day, find the probability that exactly 14 of them are spam. Round to the nearest tenth of a percent (1 decimal place percent).       Question 3 The sensitivity of a medical test is the true positive rate. In other words, the sensitivity is the probability that a person with the condition is correctly identified as having it. The specificity of a test is the true negative rate. In other words, the specificity is the probability that a person without the…
