what is the probability of rolling a sum that exceeds 4 with two dice

  • math/Probability -

    Let's take a look at what we DON"T want

    We do not want sums of 2, 3 and 4
    sum of 2 -- 1 way
    sum of 3 -- 2 ways
    sum of 4 -- 3 ways , for a total of 6 we do not want
    Since the two dice can fall in 36 ways,
    30 of them would exceed a sum of 4

    prob(your event) = 30/36 = 5/6
