Suppose 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 fallowing discrete probability function e-6 x 6* f(x) = for x = 0, 1, 2, 3... x! Find the probability that in a specific 20-second time period, less than 3 cars arrive at the inter-section. A) 0.05949 B) 0.06197 c) 0.14873 D) 0.15120
