Exercise 1 involves 8 randomly selected deaths during the time period spanning from the week before Thanksgiving to the week after Thanksgiving. Assume now that 20 deaths are randomly selected from that time period.

a. Find the probability that exactly 14 of the deaths occur during the week before Thanksgiving.

b. Is it unusual to have exactly 14 deaths occurring the week before Thanksgiving?

c. If the probability of exactly 14 deaths is very small, does that imply that 14 is an unusually high number of deaths occurring the week before Thanksgiving? Why or why not?
