What is the probability of rolling a six sided die 20 times and getting a 5?

Suppose A is the event {rolling a 6-sided die 20 times and getting a 5}
Then A', the complement of A, is the event {rolling a 6-sided die 20 times and not getting a 5 any times}
So Pr(A) = 1 - Pr(A') = 1 - (5/6)20 = 1 - 0.026084 = 0.973916 (to 6 dp)

What is the probability of rolling a 6-sided die two times and getting a 6 and then a 2?
1 in 6 times 1 in 6 equals 1 in 36
What is the probability of rolling a 6 sided dice three times and getting a 4 all three times?
1/6 times 1/6 times 1/6= 1/216 chance of getting a 4.
What is the probability of rolling at least two sixes when a fair six sided die is rolled 5 times?
It is 0.1962
What are theoretical and expierimental probability?
Theoretical probability is the probability of something occurring when the math is done out on paper or 'in theory' such as the chance of rolling a six sided dice and getting a 2 is 1/6. Experimental probability is what actually occurs during an experiment trying to determine the probability of something. If a six sided dice is rolled ten times and the results are as follows 5,2,6,2,5,3,1,4,6,1 then the probability of rolling a 2 is 1/3. The law of large numbers states the more a probability experiment is preformed the closer to the theoretical probability the results will be.
What is the probability of rolling 2 threes in a row with a single six sided die?
The probability of rolling a 3 with a standard die is 1 in 6. The probability of doing that two times in a row is 1 in 6 squared, or 1 in 36.

1 in 6 times 1 in 6 equals 1 in 36
What is the probability of rolling a 6 sided dice three times and getting a 4 all three times?
1/6 times 1/6 times 1/6= 1/216 chance of getting a 4.
What is the probability of rolling a pair of six-sided dice 25 times and getting double sixes once Give your answer as a decimal rounded to the nearest hundredth?

When rolling one die 12 times what is the probability of rolling a 2?
The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.
What is the probabilitly of rolling a 4 on a 10-sided dice?
The probability is (0.1) times (the number of faces with '4' marked on them).
What is the probability of rolling at least two sixes when a fair six sided die is rolled 5 times?
It is 0.1962

What is the theoretical probability of rolling a 5 on a number cube if it is rolled 300 times?
The theoretical probability of rolling a 5 on a standard six sided die is one in six. It does not matter how many times you roll it, however, if you roll it 300 times, the theoretical probability is that you would roll a 5 fifty times.
What is the probability of rolling 5 on a six sided die if rolled 66 times?
It is 0.99999406 approx, or pretty nearly a certainty.
What a the odds of rolling ten sided dice ten times and getting nintyfive?
