    probability question

    A quick quiz consists of a multiple-choice question with 3 possible answers followed by a multiple-choice question with 6 possible answers. If both questions are answered with random guesses, find the probability that both responses are correct.

    can I get some explanation on this one ? I'm not sure how to do it!!

    1) 3 possible answers - Probability that a random guess is correct = \frac{1}{3}

    2) 6 possible answers - Probability that a random guess is correct = \frac{1}{6}

    Probability that both responses are correct = \frac{1}{3}*\frac{1}{6}=\frac{1}{18}
