The probability of rolling a sum of 12 in a single roll of two dice is 1 in 36, or about 0.0278.
For a single roll of a pair of fair dice, the answer is 1/36.
5/36 in a single roll.
On a single roll of a fair die, the probability is 1/3.
1 out of 6 times,or 16.67% probability.
It is 1: if you roll the die often enough. On a single roll of a fair die, the probability is 1/6.
The experiment is undefined. On a single roll of eight or more normal dice the probability of getting a sum of 7 is 0.
In one roll the probability is 1/36.
It is 2/6 = 1/3
The probability of getting a 7 on one roll of a die is zero.If you meant to ask about two dice, the probability is 6 in 36, or 1 in 6.
The answer depends on how often you roll it! For one roll it is 1/6 but the probability increases to a near certainty as you increase the number of rolls.
