5) The annual number of industrial accidents occurring in a
particular manufacturing plant is known to follow a Poisson
distribution with mean 12. NEED FORMULAS TO SOLVE IN
EXCEL.
a.What is the probability of observing of observing exactly 12
accidents during the coming year?
b. What is the probability of observing no more than 12
accidents during the coming year?
c. What is the probability of observing at least 15 accidents
during the coming year?
d. What is the probability of observing between 10 and 15
accidents (including 10 and 15) during the coming year?
e. Find the smallest integer k such that we can be at least 99%
sure that the annual number of accidents occurring will be less
than k.
