The probability of a one being rolled in a fair die is 1 in 6, or 0.1666... . The probability of a one not being rolled is 5 in 6, or 0.8333... . The probability, then, of exactly one one being rolled in nine rolls is 1 in 6 times 5 in 6 to the 8th power, or about 0.0388.

What is the probability that a sum of 9 appears 13 times out of a 100 times rolled cube?
On a normal cube, the probability is 0. If there are more than 1 cubes, the answer depends on how many are being rolled for each sum.
What is the probability that a six is rolled exactly once if it is known that at least one six is rolled?
The answer depends on how many rolls. If there were n rolls, then the probability is n*(1/6)*(5/6)n-1/[1 - (5/6)n]
What is the probability of rolling 6 or less if two dice are rolled once?
The probability is 1, if the dice are rolled often enough.
Six-sided die is rolled What is the probability that either a 3 or 4 is rolled?
It can roll on 1,2,3,4,5,6 so the probability of 2/6 is ±33.33%
When a die is rolled find the probability of getting a a number larger than 2?
If it is a fair die that is rolled once, then the probability is 2/3.

If a die is rolled 6 times what is the probability of 3 appearing exactly 2 times?
1/12 possibilty.

The answer depends on how many rolls. If there were n rolls, then the probability is n*(1/6)*(5/6)n-1/[1 - (5/6)n]

When a die is rolled find the probability of getting a 5?
the probability is 1 out of 6
What is the probability that the number rolled will be greater that 4?
The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.
What is the probability of a sum of 5 being rolled if you rolled a pair of dice?
It is 1/9.
When a six sided die is rolled then what is the probability that the number rolled will be five?
It is 1/6.
If two fair dice were rolled what is the probability of them rolling a sum of six?
If you rolled 2 fair dice, the probability of having a sum of 6 is 5 over 36
