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.
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.
