    In a paper bag, 7 of the 15 marbles are yellow. In a cloth bag, 2 of the 15 marbles are yellow. If Tim randomly draws one marble from each bag, what is the probability that they are both yellow?

    Bag 1 probability of drawing yellow is 7/15
    Bag 2 probability of drawing yellow is 2/15

    Since each event is independent, we multiply each draw to get our final probability:
    P(yellow Bag 1)(yellow Bag 2) = P(Yellow Bag 1) * P(Yellow Bag 2)
    P(yellow Bag 1)(yellow Bag 2) = 7/15 * 2/15
    P(yellow Bag 1)(yellow Bag 2) = 14/225

    Since we cannot simplify this fraction anymore, our answer is 14/225
