0. It is impossible to roll a 9 on a number cube with SIX numbers.
An Experiment Consists Of Rolling A Fair Number Cube. What Is The Probability Of P9?
The probability of rolling a 9 on a cube numbered 1-6 is 0. It is impossible.
The probability of a sum of 9 on two fair number cubes is 4/36 = 1/9 ≈ 0.1111
(6+3, 5+4, 4+5, 3+6 are the 4 possibilities out of the 36 ways the cubes can fall)
