What if 2 dice are rolled 100 times what is the probability that it will be a prime number?
There are 36 permutations of two standard 6 sided dice. Of those, 15 are prime, namely 2, 3, 3, 5, 5, 5, 5, 7, 7, 7, 7, 7, 7, 11, and 11. The probability of rolling a Prime number, then, is 15 in 36, or 5 in 12, or about 0.4167. It does not matter how many times you roll the dice.

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.
What is the probability of a sum of 5 on a number cube?
The answer depends on how many times it is rolled.

How do you work out the probability that a biased dice will land on a six is 0.35?
You roll it many times. The probability that it lands on a six is the number of times that it lands on a six divided by the number of times the die has been rolled.

A number cube is rolled 2 times in a row What is the probability of rolling a 3 both times?
When a number cube is rolled twice, there are 36 possible outcomes. (1,1),(1,2),....(6,6). (3,3) occurs only once. Therefore, the probability of rolling a 3 both times is 1/36.
What is the theoretical probability of getting a 5 if a number cube is rolled 50 times?
It is approx 0.99989, that is, a near certainty.
What is the probability of a single number on a 6-sided die rolled 84 times?
-78
I rolled the dice 120 times what's the probability of getting a 6?
If you rolled a die 120 times, the probability of getting a 6 is one in six. It does not matter how many times you roll the die - the probability is still one in six - except that the long term mean will approach the theoretical value of 0.166... as the number of trials increases.
What is the experimental probability of rolling a 2 on a number cube rolled 50 times?
Well, if you rolled a number cube 50 times and got a 2, let's do some quick math. The experimental probability would be the number of times you rolled a 2 divided by the total number of rolls, which in this case is 50. So, if you got a 2, say, 10 times, the experimental probability would be 10/50, which simplifies to 1/5 or 20%. Hope that clears things up for you!
What is the probability of rolling the same number when three number cubes are rolled?
The first roll doesn't matter for probability, it just sets the number to be rolled by the other two. So: P(rolling the same number three times) = P(rolling a particular number)2 = (1/6)2 = 1/36
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.
What is the probability of getting a six then a prime number?
The probability of rolling a six and then a prime on a die is (1 in 6) times (3 in 6), which is (3 in 12), which is (1 in 4), or 0.25
