3. Conditional Probability. Assume that .05 percent of the population is sick with disease X.Doctors can check if a patient with an imperfect test. The test is 95% accurate when a patienthas the disease, and 98 % accurate when a patient does not have the disease. If the test saysthat a patient has the disease, what is the probability that they are actually sick?
