To find the probability of choosing a red marble first, then a white marble if the marbles are replaced, we need to multiply the individual probabilities of each event happening.
The probability of choosing a red marble first is 3/10 since there are 3 red marbles out of a total of 10 marbles.
After replacing the marble, there are still 10 marbles in the bag, but now 4 of them are white. So, the probability of choosing a white marble next is 4/10.
Multiplying the two probabilities together, we get:
(3/10) * (4/10) = 12/100 = 3/25
Therefore, the correct answer is 3/25 or 12/100.
