Question 1036769: Find the indicated probabilities using the geometric​ distribution, the Poisson​ distribution, or the binomial distribution. Then determine if the events are unusual. If​ convenient, use the appropriate probability table or technology to find the probabilities.

A major hurricane is a hurricane with wind speeds of 111 miles per hour or greater. During the last​ century, the mean number of major hurricanes to strike a certain​ country's mainland per year was about 0.53 Find the probability that in a given year​ (a) exactly one major hurricane will strike the​ mainland, (b) at most one major hurricane will strike the​ mainland, and​ (c) more than one major hurricane will strike the mainland.

This is a poisson distribution--mean known, rare events, probability proportional to time and theoretically an infinite number could occur.
lambda=0.53
e^(-lambda), lambda^1=e^(-0.53)(0.53)=0.3120--exactly 1
at most 1 is the probability of 0 and probability of 1: 0.5886+0.3120=0.9006.
more than 1 is the complement or 0.0994.
