Question: A certain rare form of cancer occurs in 38 children in a million, so its probability is 0.000038. In the city of Normalville there are 8,782,000 children. A poisson distribution will be used to approximate the probability that the number of cases of the disease in Normalville children is more than \(2\). Find the mean of the appropriate Pois. Dist. (the mean number of cases in groups of 8,782,000 children).
