Question 874807: 19. Find the indicated probabilities using the geometric distribution or Poisson distribution. Then determine if the events are unusual. If convenient, use a Poisson probability table or technology to find the probabilities.
A major hurricane is a hurricane with wind speeds of 111miles 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 0.62. 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.

You can put this solution on YOUR website! Poisson, average = .62
a)P(x=1)= .3335 = poissonpdf(.62,1)
b)P(x <=1)= .8715 = poissoncdf(.62,1)
c)P(x> 1) .0129 = 1 - poisson(.62,1)
