An urn contains 2 red and 3 blue marbles. Two marbles are selected at random, one after the other and with replacement, from the urn. Calculate the probability that both marbles are red.

0.16
The probability of selecting a red marble on the first draw is 2/5. Since the marbles are replaced, the probability of selecting a red marble on the second draw is also 2/5.
Therefore, the probability of both marbles being red is (2/5) * (2/5) = 4/25 = 0.16.
