The lifetime risk of developing pancreatic cancer is about one in 78 (1.28%). Let X = the number of people you ask before one says he or she has pancreatic cancer. The random variable X in this case includes only the number of trials that were failures and does not count the trial that was a success in finding a person who had the disease. X is a discrete random variable with a geometric distribution: X ~ G(178)or X ~ G(0.0128). What is the mean?
