A large lake is stocked with 10% catfish. You go out on the lake to fish, and each fish you catch that is not a catfish is thrown back into the lake. (Assume that each time you catch a fish, it is independent of the other fish you have caught.) Let X be the number of tries it takes until you catch your first catfish.
(a) What is the average (expected) value for X?
(b) What is the probability that X is at most 3?
