  1. The sample space (possible outcomes) is 1, 2, 3, 4, 5, and 6. There is 6 possible outcomes.

    A possible event is getting 3.
    There is 1 favorable outcome of getting 3 in the sample space.
    1/6 is the probability as a fraction.

    Divide the numerator by the denominator. 1 ÷ 6 = 0.17 (rounded to the nearest hundredth)
    0.17 × 100 = 17 %

    So, the probability of getting a 3 is 1/6, or 17 %.
