    Answer:

    B

    Step-by-step explanation:

    find the probability of picking the first green marble, which would be 2/10

    then afterwards once the marble is removed, it would be 1/9

    Multiply both 2/10 and 1/9 to get 0.022, which rounds to 0.02

    Answer:

    0.02

    Step-by-step explanation:

    3+5+2 = 10

    to choose 1 green the probability is 2/10 = 1/5

    if we do not replace it, then there are now 9 marbles left and only 1 green left, so 1/9

    to find them both in a row, multiply

    1/5 * 1/9 = 1/45 = 0.02222
