    1. P (P) = 8/20 = 0.4

    2. P (G) = 12/20 = 0.6

    Step-by-step explanation:

    Given;

    Number of green marbles G = 12

    Number of purple marbles P = 8

    Total T = 12+8 = 20

    The probability that you choose a purple marble P (P) is;

    P (P) = number of purple marbles/total number of marbles

    P (P) = P/T = 8/20 = 0.4

    P (P) = 0.4

    The probability that you choose a Green marble P (G) is;

    P (G) = number of Green marbles/total number of marbles

    P (G) = G/T = 12/20 = 0.6

    P (G) = 0.6
