There are a total of 5 marbles in the urn, with 3 of them being blue.
The probability of selecting a blue marble on the first draw is 3/5.
Since we are replacing the first marble and then selecting a second marble, the probability of selecting a blue marble on the second draw is also 3/5.
Therefore, the probability of selecting two blue marbles with replacement is (3/5) * (3/5) = 9/25 = 0.36.
