    The possibility of rolling a 2 is 1/6, since there is one option out of 6.

    The possibility of rolling an odd number is 3/6, or 1/2, since half of the numbers are odd.

    Multiply these two together by multiplying the numerators together and multiplying the denominators together.

    (1 * 1) / (6 * 2)

    1 / (6 * 2)

    1/12
