Testing for this infection is available, but the test result is known to be 90% accurate when patient is actually infected, and 95% accurate if patient is actually not infected. James has tested once, and the result was positive. He is going to be tested two more times. Given the fact that he tested positive once, calculate the probability that the second and third tests will come back negative and positive in that order. A .09 B .14 C .16 D .29 E .41 Plzzz explain.
