    To find the probability of both of these occurring, you will multiply the probability of choosing a blue marble by the probability of choosing a purple marble (with no replacement after the first one).

    Probability of choosing a blue marble: 17/120

    Probability of choosing a purple marble: 18/119

    17/120 x 18/119 = 3/140

    You will have a 3/140 chance of both of these occurring.
