Depends on what you are rolling - a cubic die or a more exotic shape.

What is the probability of getting a two on one dice?
Total number of possible rolls with 2 dice = 36.Total number of rolls that are doubles = 6.Probability of rolling doubles= 6/36 = 1/6 = (16 and 2/3) percent .
What are the odds of rolling doubles with one die in 25 rolls?
I'm going to assume you mean rolling the same number twice in a row in 25 rolls. The first won't cause a double, so you just need to consider the odds of rolling the same number as the last for the last 24 rolls. The easier approach is to realize that the probability of rolling at least one double is 1 minus the probability of rolling no doubles. One roll has this probability of not rolling the same as the last: P(different number from last) = 5/6 Since they are independent events: P(no doubles in 25 rolls) = (5/6)24 Now the final probability, of at least one double, is 1 - (5/6)24
What is the probability of not rolling a 6 on a number cube?
The probability of not rolling it ever is 0.For n rolls it is (5/6)n sofor 10 rolls it is 0.1615for 20 rolls it is 2.608*10-2for 100 rolls it is 1.207*10-8 and so on.
What is the probability of rolling a 6 and then a 1 on consecutive rolls of a standard sided number cube?
If you keep rolling the die, then the probability of rolling a 6 and then a 1 on consecutive rolls is 1.The probability is 1/36 for the first two throws.
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]
If a die is rolled 3 times what is probability of getting an even number?
The probability of getting an even number on at least one of the 3 rolls is 7/8.
A dice is rolled three times the probability of getting at least one odd number is?
Possible outcomes of one roll = 6.Probability of an even number on one roll = 3/6 = 0.5 .Probability of an even number on the second roll = 0.5 .Probability of an even number on the third roll = 0.5 .Probability of an even number on all three rolls = (0.5 x 0.5 x 0.5) = 0.125 = 1/8The probability of at least one odd number is the probability of not gettingan even number on all 3 rolls. That's (1 - 1/8) = 7/8 or 0.875 or 87.5% .
What is the probability of getting a two on one dice?
Total number of possible rolls with 2 dice = 36.Total number of rolls that are doubles = 6.Probability of rolling doubles= 6/36 = 1/6 = (16 and 2/3) percent .
What is the probability of rollling a 5 3times ina row?
With a fair die, it is 1/216 in three rolls, but the probability increases to 1 (a certainty) as the number of rolls is increased.

When two dice are rolled what is the probability that both will be a five?
if you multiply the number of rolls you did you will get the answer
What is the probability of rolling a 6 and then a 1 on consecutive rolls of a standard sided number cube?
If you keep rolling the die, then the probability of rolling a 6 and then a 1 on consecutive rolls is 1.The probability is 1/36 for the first two throws.
What is the probability of rolling a sum less than 9 with two dice?
There are twenty six ways out of thirty six possible rolls of two dice to hit a number less than nine OR a seventy two percent probability.
What is the probability of rolling a 1 and a prime number?
If the die is rolled often enough, the probability is 1. With only two rolls of a fair die, the probability is 1/6.
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]
A random variable and a probability distribution?
The number of 6s in 37 rolls of a loaded die and binomial.
