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

What is the probability of getting a sum of seven in rolling two dice?

To find the probability of rolling a sum of seven with two dice, we first determine the total number of possible outcomes, which is 6 (for the first die) multiplied by 6 (for the second die), resulting in 36 possible outcomes. The combinations that yield a sum of seven are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1), totaling 6 favorable outcomes. Therefore, the probability of rolling a sum of seven is 6 favorable outcomes divided by 36 possible outcomes, which simplifies to 1/6.


What is the probability of rolling a 4 or 5 on a six sided cube?

The chance of rolling a certain number on a dice is 1/6, so the chance of rolling a 4 OR 5is 2/6. But if you have two dice you have the most chance of rolling a seven (6/36 or 1/6)


What is the probability of rolling a seven on one roll of a die?

impossible. there are only 6 numbers on a die.
