Question

two number cubes are rolled 3 times in a row. what is the probability of rolling a sum of 9 all three times?

Answer 1

1/216 or 1:216 or about .5%

Explanation:

Each roll has a 1/6th chance of being a nine. Roll the dice three times, and you get

simplify it down to

1/36 × 1/6

solve to get the answer of

1/216
