a diagnostic test for a disease is such that it (correctly) detects the disease in 90% of the individuals who have the disease. also, if a person does not have the disease, the test will report that he or she does not have it with probability 0.9. only 1% of the population has the disease in question. if a person is chosen at random from the population and the diagnostic test indicates that she has the disease, what is the conditional probability that she does, in fact, have the disease?
