Use the following information for questions:
John and Mary both leave for class at the same time. The time it takes them to get to class, (J = time for John, M = time for Mary) are independent normal random variables. For John, the mean time E(J) = 10 minutes with variance V(J) = 4 minutes. For Mary, the mean time E(M) = 8 minutes with variance V(M) = 1 minute.
-What is the probability that Mary will get to class before John does?
