The probability that a person has a certain disease is 0.03. Medical diagnostic tests are available to determine whether the person actually has the disease. If the disease is actually present, the probability that the medical diagnostic test will give a positive result (indicating that the disease is present) is 0.9. If the disease is not actually present, the probability of a positive test result (indicating that the disease is present) is 0.02.a) Suppose that the medical diagnostic test has given a positive result (indicating that the disease is present), what is the probability that the disease is actually present?b) What is the probability of a positive test result?

Here are 100 seats on an airplane, and each of 100 passengers has a ticket for a different seat. The passengers line up to board the plane, but just before boarding, the first passenger loses his ticket. Since he has no idea where to sit, he chooses aseat uniformly at random from the 100 seats. Each subsequent passenger first goes to their assignedseat. If that seat is empty, then they sit down, but if it is occupied then they choose a seat at randomfrom the remaining empty seats. This proceeds until the last person boards the plane. What is the probability that the last person gets to sit in their assigned seat?
