    The probability that a 2 or 3 is rolled at least once is 0.14.

    Probability of not rolling a 2 or 3 in a single die roll of two dice

    when a six die is rolled once there is 11/12 probability of not rolling 2 or 3.
    rolling a six sided die two times, p(2 or 3)’ = 11/12
    rolling a six sided die four times, p(2 or 3)’  = (11/12)² = 121/144
    the probability that a 2 or 3 is rolled at least once is calculated as follows;
    P = 1 – p(2 or 3)’
    P = 1 – 121/144
    P = 20/144
    P = 0.14
    Thus, the probability that a 2 or 3 is rolled at least once is 0.14.
