A certain area in the Southeastern United States is hit by an average of 2.1 tropical storms per year.

            Assume that tropical storms occur randomly and independently and can be modelled as a Poisson random

variable.

            a.   Find the probability that for a given year the area will be hit by two or more tropical storms.

            b.   Find the probability that there is at least one tropical storm in each of the next three years.

IN part b do we multyply lambda by 3 to account each of the next 3 years?
