➷ This problem involves dependent probability, because you DO NOT replace the marble.

First, you need to find the probability of getting a green marble on the first draw:

7/20 because there are 7 green marbles and 20 marbles total.

Next, you need to find the probability of getting a green marble on the second draw:

6/19 because you took out one green marble there are 6 left and 19 total marbles left.

Then, to get your final probability, multiply the two fractions together:

7/20*6/19=21/190

Final

The probability of getting two green marbles without replacing them is 21/190.
