What are the odds of rolling two number cubes and getting a sum of seven?

Number of possible outcomes of one cube = 6 Number of possible outcomes of the other cube = 6 Number of possible outcomes of two cubes = 6 x 6 = 36 Number of ways to roll a sum of 7 with two cubes = 6 1 - 6 2 - 5 3 - 4 4 - 3 5 - 2 6 - 1 Probability of rolling the sum of 7 = 6/36 = 1/6 = (16 and 2/3) percent
