A department store is holding a drawing to give away free shopping sprees. There are 10 customers who have entered the drawing:3 live in the town of Gaston, 2 live in Pike, and 5 live in Wells. Two winners will be selected at random. What is the probability that both winners live in Pike? Write your answer as a fraction in simplest form.
prob(your event) = (2/10)(1/9) = 1/45
or
prob(your event) = C(2,2)/C(10,2) = 1/45
