A bag has four green marbles, three red marbles, and three yellow marbles. What is the probability that you pick a red marble, do not replace it, and pick another red marble?

A. 2/15

B. 1/15

C. 1/9

D. 3/10

Hey there, we need to find a red marble, there are three red marbles, so we need to make a fraction, 3 is the denominator. Now, we need to add up all of the marbles and that will be our numerator, 4+3+3=10. So, the fraction would be 3/10, Therefore, the answer is D. 3/10
