So the number of green marble is 7.
The total amount of marbles are 16.
The probability of choosing a green marble is 7/16 on the first try.
Now without replacement, we have a total amount of 6 green marbles and 15 total marbles, altogether.
So the probability of choosing a green for the second time, without replacement is 6/15.
To find both the probabilities combined, multiply them together:
This would be 7/16 * 6/15.
This would result in 0.175 in the calculator.
