12. The annual rainfall (in inches) in a certain region is normally distributed with u = 40 inches and o2 = 16. Assume that the rainfall of any year is independent of other years. What is the probability that, starting with this year, it will take over 10 years before a year occurs having a rainfall of over 50 inches?
