The size of fish in a lake follows a Normal Distribution with mean m = 1 lb 4 oz and standard deviation s = 3 oz . Fish that weigh less than 1 lb 9 oz must be released back into the lake. Bill wants to reach his limit of 5 "keepers." What is the probability that Bill must catch at least 40 fish in order to reach his limit.
