Finding Probabilities of Compound Events
A bag contains 2 red marbles and 3 black marbles. If Abby picks a marble without looking, returns it to the bag, and then draws a second marble, what is the probability that both marbles are red? Write your answer as a fraction.

P(both red) = (2/5) × (2/5) = 4/25.
