2. Suppose that earthquakes occur in a certain region of California, in accordance with a Poisson process, at a rate of seven per year. Assume that all required conditions for the Poisson process hold. a. What is the probability that in exactly three of the next eight years no earthquakes will occur? b. Approximate the probability that at most 3 of the next 30 years no earthquakes will occur by using an appropriate Poisson distribution.
