There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.

1 Expert Answer The number of different outcomes on two dice is the number of different outcomes on the first die (6) TIMES the number of different outcomes on the second (6), or 36. The probability of rolling doubles is 1/6, because there are 6 ways to roll doubles. 6/36 = 36.
Probabilities for the two dice
Total | Number of combinations | Probability |
---|---|---|
10 | 3 | 8.33% |
11 | 2 | 5.56% |
12 | 1 | 2.78% |
Total | 36 | 100% |
Two (6-sided) dice roll probability table
Roll a… | Probability |
---|---|
4 | 3/36 (8.333%) |
5 | 4/36 (11.111%) |
6 | 5/36 (13.889%) |
7 | 6/36 (16.667%) |
How many total combinations are possible from rolling two dice? Since each die has 6 values, there are 6∗6=36 6 ∗ 6 = 36 total combinations we could get.
So the probability of rolling a 2 and a 3 would be 1/36 + 1/36 = 2/36 or 1/18. There is only one way to roll two 6’s on a pair of dice: the first die must be a 6 and the second die must be a 6. The probability is 1/6 × 1/6 = 1/36. There are 3 ways in which to get at least one 6 in the roll of two dice.
