An analyst for a propane company has analyzed demand for tanks of propane over the previous 5 years and noted a strong rise in demand during months in which there are severe storms (hurricanes, tornados, etc.) due to people without power using propane to cook and heat with propane. Furthermore, the analyst has noted that in one region the probability of a severe storm is approximately 10% each month.
a. Assuming a Binomial distribution, what is the probability of no storms in that region in a year?
b. Assuming a Binomial distribution, what is the probability of more than one storm in that region in a year?
c. Assuming a Poisson distribution, what is the probability of no storms in that region in a year?
d. Assuming a Poisson distribution, what is the probability of more than one storm in that region in a year?
