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 the first marble is red and the second is blue.

The probability of selecting a red marble followed by a blue marble can be calculated as follows:
Probability of selecting a red marble first = 2/5
Probability of selecting a blue marble second = 3/5
Therefore, the probability of selecting a red marble first and then a blue marble is (2/5) * (3/5) = 6/25 = 0.24
