Many companies are now testing prospective employees for drug use. However, opponents claim that this procedure is unfair because the tests themselves are not 100% reliable. Suppose a company uses a test that is 93.7% accurate - that is, it correctly identifies a person as a drug user or nonuser with probability of 93.7% - and to reduce the chance of error, each job applicant is required to take two tests. Note that an applicant can only pass the drug test if he/she passes both tests. If the outcomes of the two tests on the same person are independent events, what is the probability that a nonuser fails the drug test
