    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%.
