Probabilities of this Dice Roller

2D6

Probability of getting a 1

In technical terms this is equivalent of getting atleast one 1. This is close to 0.31, about 30.56% percent.

This is calculated by multiplying all the probabilities of not getting a 1 for each dice and then subtracting the answer from 1.

1 - (5/6 x 5/6)

Probability of not getting a 1

Probability of not getting any 1 is close to 0.69, about 69.44% percent.

This is calculated by multiplying all the probabilities of not getting a 1 for each dice.

5/6 x 5/6

Probability of getting all 1's

Probability of getting all 1's is close to 0.028, about 2.78% percent.

This is calculated by multiplying together all the probabilities of getting a 1 for each dice.

1/6 x 1/6

Probability of getting 2 1s

Probability of getting 2 1's is close to 0.028, about 2.78% percent.

This is calculated by multiplying together all the probabilities of getting a 1 for each dice that has a 1.

1/6 x 1/6

Probability of getting a 6

In technical terms this is equivalent of getting atleast one 6. This is close to 0.31, about 30.56% percent.

This is calculated by multiplying all the probabilities of not getting a 6 for each dice and then subtracting the answer from 1.

1 - (5/6 x 5/6)

Probability of not getting a 6

Probability of not getting any 6 is close to 0.69, about 69.44% percent.

This is calculated by multiplying all the probabilities of not getting a 6 for each dice.

5/6 x 5/6

Probability of getting all 6's

Probability of getting all 6's is close to 0.028, about 2.78% percent.

This is calculated by multiplying together all the probabilities of getting a 6 for each dice.

1/6 x 1/6

Probability of getting 2 6s

Probability of getting 2 6's is close to 0.028, about 2.78% percent.

This is calculated by multiplying together all the probabilities of getting a 6 for each dice that has a 6.

1/6 x 1/6

Probability of getting all highest faces

Probability of getting all the maximum faces (2 6's) is close to 0.028, about 2.78% percent.

This is calculated by multiplying together all the probabilities of getting the maximum face for each dice.

1/6 x 1/6

Probability of getting one of a kind

Probability of getting one of a kind is close to 0.17, about 16.67% percent.

There are 6 ways to get one of a kind (all 1's, all 2's, all 3's, all 4's, all 5's or all 6's). The probability of getting all of any kind is then caclulated by adding the probability of getting all 1's, all 2's, all 3's, all 4's, all 5's or all 6's. Since, probabilities of getting all 1's through all 6's are the same, we can multiply them all together. So, multiplying the probability of getting all 1's by 6 will give us the probability of getting all of any kind.
