Abag 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
