Answer:

4.9%

Step-by-step explanation:

There are a total of 20 marbles.

The probability that the first marble is green is 8/20.

The probability that the second marble is green is 7/19.

The probability that the third marble is green is 6/18.

The total probability is:

P = (8/20) (7/19) (6/18)

P ≈ 0.049

The probability is 4.9%.
