The probability of of rolling three ones on three dice is (1 in 6)3, or 1 in 216, or about 0.004630.
With one roll of three dice, the probability is 7/8.
The answer depends on what you are rolling: three or more ordinary dice, or fewer dice with non-standard numbers on them, or a die with some other shape.
The probability of rolling two prime numbers on a standard pair of dice is 1 in 4, or 0.25. Take the probability of rolling a prime on one die, 3 in 6, or 1 in 2, or 0.5, and square it.
The probability of rolling doubles with two dice is 1 in 6, or about 0.167.
The probability of of rolling three ones on three dice is (1 in 6)3, or 1 in 216, or about 0.004630.
If the numbers are 1 to 6, there are three prime numbers in that range, a probability of 50%.
With one roll of three dice, the probability is 7/8.
The probability of rolling two even numbers on two standard dice is 0.52, or 0.25.
The answer depends on what you are rolling: three or more ordinary dice, or fewer dice with non-standard numbers on them, or a die with some other shape.
5/216
It is 1/4.
The probability of rolling two prime numbers on a standard pair of dice is 1 in 4, or 0.25. Take the probability of rolling a prime on one die, 3 in 6, or 1 in 2, or 0.5, and square it.
There are 36 permutations of rolling two dice. Three of them, (4,6), (5,5), and (6,4) add up to ten. Therefore, the probability of rolling ten on two dice is 3 in 36, or 1 in 12, or about 0.0833.
Rolling it once there is a 1 out of 6 chance - because there is 6 numbers on a dice and one of them is three. so rolling it twice would be a 2 out of 12 chance / 0.16 / 16% chance
1:6
The probability of rolling doubles with two dice is 1 in 6, or about 0.167.
