The first pull has a probability of 5/19 of getting a green marble, the second pull has a probability of 4/18 (since there are now only 4 green marbles left out of 18 total marbles), and the third pull has a probability of 3/17.
Therefore, the probability that all three pulls are green is:
(5/19) * (4/18) * (3/17) = 60 / 586.
Therefore, the probability that all three pulls are green is:
(5/19) * (4/18) * (3/17) = 60 / 586.
