    Step-by-step explanation:

    There are a total of 17 marbles, 8 of which are red.

    The probability that the first marble is red is 8/17.

    The probability that the second marble is red is 7/16.

    The probability that the third marble is red is 6/15.

    Therefore, the probability that all three marbles are red is:

    P = 8/17 * 7/16 * 6/15

    P = 7/85

    P = 0.082
