    Step-by-step explanation:

    7 red marbles, 3 blue marbles and 8 green marbles = 18 marbles

    P (green) = green/total = 8/18 = 4/9

    Keep marble

    7 red marbles, 3 blue marbles and 7 green marbles = 17 marbles

    P (green) = green/total = 7/17

    Keep marble

    7 red marbles, 3 blue marbles and 6 green marbles = 16 marbles

    P (green) = green/total = 6/16 = 3/8

    P (green, green, green) = 4/9*7/17 * 3/8 = 7/102

    To the nearest tenth of a percent

    .068627451 = 6.8627451% = 6.9%
