Question

A. A bag contains 4 red marbles, 5 yellows marbles, and 7 whites marbles. If a marble is drawn from the bag, replaced, and another marble is drawn,

what is the probability of drawing first a marble and then a marble?

Answer 1

Answer: 5/64

Explanation:

The probability of drawing a red marble on the first draw is 4/16 = 1/4 (since there are 4 red marbles out of 16 total marbles).

After replacing the first marble, the probability of drawing a yellow marble on the second draw is 5/16 (since there are 5 yellow marbles remaining out of 16 total marbles).

Therefore, the probability of drawing a red marble and then a yellow marble is (1/4) x (5/16) = 5/64
