Problem 3: probability of disease clusters. Suppose a building has 100 people. Assume that for one person the probability of developing a cancer over 10 years is 10%. Thus in a building on average we expect 10 cases over 10 years. Let's say that a building has a disease cluster if there are more than 20 cases over that period. (1) Use the CLT to estimate probability of a cluster in a building. Tick of
