    Answer:

    1/10

    Step-by-step explanation:

    four green marbles, three red marbles, and three yellow marbles

    Original total number of marbles: 4 + 3 + 3 = 10

    First pick

    Picking a red marble. There are 3 red marbles.

    p(red) = 3/10

    Second pick

    Since the red marble picked is not replaced, now the total is 9 marbles.

    Picking a yellow marble. There are 3 yellow marbles.

    p(yellow) = 3/9 = 1/3

    The probability of both events is the product of the individual probabilities.

    p(red then yellow) = 3/10 * 1/3 = 1/10
