Hello everyone I wish to know the formula for calculating how

>>378336
>to get a double
Any double.
1* 1/10. The first roll counts only for the number you are aiming for, anything 0-9. Therefore the probability is 1. The second roll (regardless of it being the second or third dice) needs to repeat the first roll with a probability of one out of ten. Therefore 1/10. You didn't put restrictions on which double, nor you didn't put restrictions for Only double. You wanted only any double.

>And a triple
Any triple. 1 * 1/10 * 1/10. Same thing, the first roll is allowed to be anything, therefore 1. The second and third roll need both to repeat the first roll with a probability of one out of them for both, so you multiply those. You didn't put restrictions on which triple.

It's just the number of possibilities for each roll, multiplied together.

For double anything: 1 (possibility for the first roll) * 10 (possibilities for the second roll) = 10 possibilities, so 1 in 10

For triple anything: 1 (possibility for the first roll) * 10 (possibilities for the second roll) * 10 (possibilities for the third roll) = 100 possibilities, so 1 in 100

For double something, e.g. double 7s: 10 (possibilities for the first roll) * 10 (possibilities for the second roll) = 100 possibilities, so 1 in 100

For triple something, e.g. triple 7s: 10 (possibilities for the first roll) * 10 (possibilities for the second roll) * 10 (possibilities for the third roll) = 1,000 possibilities, so 1 in 1,000
