9 Ship collisions in the Vancouver harbor are rare. Suppose the number of collisions is Poisson distributed, with a mean of 1.2 collisions every four months. a. b. c. What is the probability of having no collisions occur over a four-month period? What is the probability of having exactly two collisions in a two-month period? What is the probability of having one or fewer collisions in a six-month period? If this outcome occurred, what might you conclude about harbor conditions during this period? What might you conclude about harbor safety awareness during this period? What might you conclude about weather conditions during this period? What might you conclude about lambda
