In "Boston Record Game Fishes", it is stated that in the Cozumel region, approximately 40% of strikes (while trolling) result in a catch. Suppose that on a given day a fleet of fishing boats got a total of 35 strikes. What is the probability that the number of fish caught was:
(A) 10 or more?
(B) 20 or fewer?
(C) between 10 and 20?
(HINT: can this binomial distribution be approximated by a normal distribution)
