The mean number of organ transplants from living donors performed per day in the United States in 2016 was about 16. Find the probability that the number of organ transplants from living donors performed on any given day is 

(a) Exactly 12, 

(b) At least eight, and 

(c) No more than 10.

Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine whether the events are unusual. If convenient, use a table or technology to find the probabilities.
