12. Suppose that it is known from large amounts of historical data that X, the number of cars that arrive at a specific intersection during a 20-second time period, is characterized by the following discrete probability function: P(X = x) = e-6 5 for x = 0, 1,2, . Find the probability that in a specific 20-second time period, only two cars arrive at the intersection.
