The probability of choosing a red marble on the first draw is 3/10, since there are 3 red marbles out of a total of 10 marbles.
If the marbles are replaced after the first draw, the probability of choosing a white marble on the second draw is 4/10, since there are 4 white marbles out of a total of 10 marbles.
To find the probability of both events happening, we multiply the individual probabilities:
P(red, then white) = P(red) * P(white) = (3/10) * (4/10) = 12/100 = 0.12
Therefore, the probability of choosing a red marble, then a white marble if the marbles are replaced is 0.12.
