What is the probability that you pick a green marble, do not replace it, and pick a red marble Please Help

I choose 1/9 because there is 10 marbles total and if you select one and do not replace it there would obviously be 9 left.

OpenStudy (anonymous):

3/10 to pick a red 1/3 to pick a yellow because there is 3 yellow in the bag and 9 total 9/3=3

OpenStudy (anonymous):

so the answer is 3/10?

OpenStudy (anonymous):

2/5 to pick a green 1/3 to pick a red

OpenStudy (anonymous):

id pick 1/3

OpenStudy (anonymous):

1/3 isn't a option. The answers are A:2/15 B:1/15 C:1/9 D:3/10 E: 1/10 for both questions

OpenStudy (anonymous):
