Step-by-step explanation:
First, find the probability that you will pull a yellow marble. There are 9 yellow marbles and 22 total, so the probability is 9/22. Then, find the probability that you will pull a green marble. There are 7 green out of 22 so the probability is 7/22. To find the probability of both, multiply them.
9/22 * 7/22 is 63/484
