An urn contains 2 red and 3 blue marbles. Two marbles are selected at random, one after the other and without replacement, from the urn. Calculate the probability that the first marble is blue and the second is red.

0.3
The probability of selecting a blue marble first is 3/5. After selecting a blue marble, there will be 2 red and 2 blue marbles left. The probability of selecting a red marble second is 2/4.
To find the overall probability, we multiply the individual probabilities:
(3/5) * (2/4) = 6/20 = 0.3
Therefore, the probability that the first marble is blue and the second is red is 0.3.
