A certain rare form of cancer occurs in 37 children in a million, so its probability is 0.000037. In the
  city of Normalville there are 74,090,000 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 Poisson distribution (the mean number of cases in
  groups of 74,090,000 children).
  A) 27,400 B) 2740 C) 274 D) 0.000037

Question 2

On a multiple choice test with 17 questions, each question has four possible answers, one of which
