A test is designed to detect cancer. If a person has cancer, then the probability that the test will detect it is .95; if the person does not have cancer, the probability that the test will erroneously indicate that he or she does have cancer is 0.1. Assume 15% of the population who take the test have cancer. What is the probability that a person described by the test as not having cancer really does have it?
