Probabilities of this Dice Roller

2D47

Probability of getting a 1

In technical terms this is equivalent of getting atleast one 1. This is close to 0.042, about 4.21% 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 - (46/47 x 46/47)

Probability of not getting a 1

Probability of not getting any 1 is close to 0.96, about 95.79% percent.

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

46/47 x 46/47

Probability of getting all 1's

Probability of getting all 1's is close to 0.00045, about 0.045% percent.

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

1/47 x 1/47

Probability of getting 2 1s

Probability of getting 2 1's is close to 0.00045, about 0.045% percent.

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

1/47 x 1/47

Probability of getting a 47

In technical terms this is equivalent of getting atleast one 47. This is close to 0.042, about 4.21% percent.

This is calculated by multiplying all the probabilities of not getting a 47 for each dice and then subtracting the answer from 1.

1 - (46/47 x 46/47)

Probability of not getting a 47

Probability of not getting any 47 is close to 0.96, about 95.79% percent.

This is calculated by multiplying all the probabilities of not getting a 47 for each dice.

46/47 x 46/47

Probability of getting all 47's

Probability of getting all 47's is close to 0.00045, about 0.045% percent.

This is calculated by multiplying together all the probabilities of getting a 47 for each dice.

1/47 x 1/47

Probability of getting 2 47s

Probability of getting 2 47's is close to 0.00045, about 0.045% percent.

This is calculated by multiplying together all the probabilities of getting a 47 for each dice that has a 47.

1/47 x 1/47

Probability of getting all highest faces

Probability of getting all the maximum faces (2 47's) is close to 0.00045, about 0.045% percent.

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

1/47 x 1/47

Probability of getting one of a kind

Probability of getting one of a kind is close to 0.021, about 2.13% percent.

There are 47 ways to get one of a kind (all 1's, all 2's, all 3's, all 4's, all 5's, all 6's, all 7's, all 8's, all 9's, all 10's, all 11's, all 12's, all 13's, all 14's, all 15's, all 16's, all 17's, all 18's, all 19's or all 20's and so on). 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, all 6's, all 7's, all 8's, all 9's, all 10's, all 11's, all 12's, all 13's, all 14's, all 15's, all 16's, all 17's, all 18's, all 19's or all 20's and so on. Since, probabilities of getting all 1's through all 47's are the same, we can multiply them all together. So, multiplying the probability of getting all 1's by 47 will give us the probability of getting all of any kind.
