    14/95

    Step-by-step explanation:

    5 red, 8 blue, and 7 green = 20 marbles

    P (blue) = blue/total = 8/20 = 2/5

    No replacement

    5 red, 7 blue, and 7 green = 19 marbles

    P (blue) = blue/total = 7/19

    P (blue, no replacement, blue) = 2/5 * 7/19 = 14/95

    Step-by-step explanation:

    5 (red) marbles+8 (blue) marbles+7 (green) marbles = 20 total marbles

    The probability of getting blue can be written as 8/20 or 4/10

    Since you arent replacing any marbles, you have to multiply 4/10*4/10

    =4/25
