1. Suppose that 30% of all drivers stop at an intersection having flashing red lights when no other cars are visible. Let X denote the number of those that stop. Of 14 randomly selected drivers coming to the intersection calculate the following. (a) Find P(3< X <8) (b) Use the Poisson distribution to approximate the probability in (a). (c) Calculate the absolute error in your approximation. Explain why your answer in (b) is so poor.
