Probabilities of this Dice Roller

D2

Probability of getting a 1

In technical terms this is equivalent of getting atleast one 1. This is close to 0.5, about 50% 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 - (1/2)

Probability of not getting a 1

Probability of not getting any 1 is close to 0.5, about 50% percent.

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

1/2

Probability of getting all 1's

Probability of getting all 1's is close to 0.5, about 50% percent.

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

1/2

Probability of getting 1 1s

Probability of getting 1 1's is close to 0.5, about 50% percent.

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