Question

Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 7.1 per year.

a. Find the probability that, in a year, there will be 5 hurricanes.

b. In a 45 year period, how many years are expected to have 5 hurricanes?

c. How does the result from part (b) compare to a recent period of 45 years in which 5 years had 5 hurricanes? Does the Poisson distribution work well here?

Assume that the Poisson distribution applies and that the mean
number of hurricanes in a certain area is 5.2 per year.
a. Find the probability that, in a year, there will be 4
hurricanes.
b. In a 35-year period, how many years are expected to have 4
hurricanes?
c. How does the result from part (b) compare to a recent period
of 35 years in which 5 years had 4 hurricanes? Does the Poisson
distribution work well here?

Assume that the Poisson distribution applies and that the mean
number of aircraft accidents is 10 per month. Find P(0), the
probability that in a month, there will be no aircraft accidents.
Is it unlikely to have a month with no aircraft accidents?

Struggling with Poisson Distribution. Please could you explain
the calculation?
Assume that a number of network errors experienced in a day in a
local area network are distributed as a Poisson random variable.
The mean number of network errors experienced in a day is 1.6.
1) Work out the probability that in any given day more than two
network errors will occur
2) Work out the probability that in any given day two or more
network errors will occur
3)...
