1) A surgeon has found that she can model the number of surgeries done per week with a Poisson distribution in which = 20.9. How many surgeries would be expected in a year? Assume no vacation or time off.

2) Suppose that 2% of a population has a virus. You test 872 people. You wish to find the probability that 19 of the people in the sample have the virus. Use the Poisson distribution and the formula =np from the Binomial distribution to approximate this probability.
