This is calculated by multiplying all the probabilities of not getting a 1 for each dice and then subtracting the answer from 1.
1 - (130/131)
This is calculated by multiplying all the probabilities of not getting a 1 for each dice.
130/131
Probability of getting all 1's is close to 0.0076, about 0.76% percent.
This is calculated by multiplying together all the probabilities of getting a 1 for each dice.
