A medical test is used to detect a particular disease. Suppose that 0.2% of the population has the disease. If a person has the disease, there is a 97% chance that the test result will be positive. If the person is healthy, there is a 4% chance that the test result will be positive. Given that a person is selected at random and the test indicates a positive result, what is the probability that the person selected has the disease?
