A fair die is rolled 9 times compute the probability that a one appears exactly once?
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.
If a number cube is rolled 4 times what is the probability that the same number is rolled at least twice?
It is 0.722... recurring.
A dice is rolled 12 times What is the probability of at least two 5's appearing?
The probability is 0.6187, approx.
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 of a sum of 5 on a number cube?
The answer depends on how many times it is rolled.
A dice is rolled three times in succession what is the probability of rolling three sixes?
The probability of rolling a six is one in six. The probability of rolling three consecutive sixes is one in 216. (1/6 x 1/6 x 1/6 = 1/216)

What is the probability of a sum of 5 on a number cube?
The answer depends on how many times it is rolled.
Suppose a die is rolled 400 times and the number of times a 5 is rolled is 60 Calculate the empirical probability of rolling a 5 based on this data?
15
If a hexahedral die is rolled two times what is the probability of not rolling a five both times?
25/36
If 3 dice were rolled 1000 times what is the probability of rolling a 14?
The probability that 14 is rolled at least once is 1 - 5.5*10-32 which, for all intents and purposes, can be treated as 1.
If a die is rolled 3 times what is the probability of having a sum of 5?
3_18 3_18
If a die is rolled 6 times what is the probability of 3 appearing exactly 2 times?
1/12 possibilty.
