A bag contains 4 white, 3 blue, and 3 red marbles. Find the probability of choosing a red marble, then a white marble if the marbles are replaced.

7/100
12/90
12/100

Answer 1

The probability of choosing a red marble first is 3/10 (3 red marbles out of 10 total marbles).

After replacing the marble, the probability of choosing a white marble is 4/10 (4 white marbles out of 10 total marbles).

To find the combined probability, we multiply the individual probabilities:

(3/10) * (4/10) = 12/100 = 3/25

Therefore, the probability of choosing a red marble, then a white marble if the marbles are replaced is 3/25 or 12/100.
