Problem 15BSC

Pre-Employment Drug Screening. In Exercises 13–16, use the test results summarized in Table 41, reproduced here. Consider an event to be “unlikely” if its probability is 0.05 or less.

Pre-Employment Drug Screening If 3 of the 1000 test subjects are randomly selected, find the probability that they all had correct test results (either true positive or true negative). Is such an event unlikely?

a. Assume that the 3 selections are made with replacement.
