D 1/5
B 1/2
There are a total of 10 marbles in the bag. The probability of choosing a red marble on the first draw is 5/10 = 1/2. Since the marble is replaced, the total number of marbles remains the same for the second draw. The probability of choosing a green marble on the second draw is 2/10 = 1/5. Therefore, the probability of choosing a red marble and then a green marble with replacement is 1/2 * 1/5 = 1/2.
