The probability of choosing a red marble on the first draw is 5/12. Since the marbles are replaced, the probability of choosing a white marble on the second draw is also 4/12 or 1/3.
To find the probability of both events happening together (i.e. choosing a red marble and then a white marble), we multiply the probabilities:
5/12 * 1/3 = 5/36
So the answer is B. five over thirty-six.
A bag contains 4 white, 3 blue, and 5 red marbles.
Find the probability of choosing a red marble, then a white marble if the marbles are replaced.
A. one-twelfth
B. five over thirty-six
