What is the probability of rolling a sum of 5 or 6 when you roll two number cubes?

There are 36 permutations of two dice. Of those, 9 add up to a sum of 5 or 6...
1 + 4 = 5
2 + 3 = 5
3 + 2 = 5
4 + 1 = 5
1 + 5 = 6
2 + 4 = 6
3 + 3 = 6
4 + 2 = 6
5 + 1 = 6
The probability, then, of rolling a 5 or 6 with two dice is 9 in 36, or 1 in 4, or 0.25.

When rolling two six sided number cubes the probability that on one roll you get at least a nine?
It is 5/18.
What is the probability that a roll of 2 number cubes roll a sum of 24?
If they are standard cubes - with numbers from 1 to 6 - the probability is 0.
When rolling 1 dice what is the probability of rolling number 4?
It is 1 (a certainty) if you roll it often enough. For a single roll of a fair die, the probability is 1/6.
What is the probability of rolling a 5 on a roll of a single number cube?
The probability of rolling a 5 on a roll of a single number cube is 1/6 (0.1666) as there is only one number 5 on a total of 6 sides on the cube.
WhaT Is thE probability of getting a sum of 13 with one roll of a pair of fair number cubes 1-6?
The probability is 0.
When rolling two six sided number cubes the probability that on one roll you get at least a nine?
It is 5/18.
What is the probability of rolling a 2 and then a 3 with 6-sised cubes?
The probability of rolling a 2 on the first roll is 1 in 6. The probability of rolling a 3 on the second roll is 1 in 6. However, the probability of rolling a 2 on the first roll and 3 on the second roll before you roll at all is 1/6 x 1/6 = 1 in 36.
What is the probability that a roll of 2 number cubes roll a sum of 24?
If they are standard cubes - with numbers from 1 to 6 - the probability is 0.
If you roll a pair of six sided number cubes what is the probability of rolling two numbers whose sum is 6?
If you roll a pair of six sided number cubes the probability of rolling two numbers whose sum is 6 is 5/36 or 0.1389. There are 5 ways to get 6: 1,5 & 5,1 & 4,2 & 2,4 & 3,3. There are 36 outcomes for a roll of 2 dice.
What is the probability of rolling a 7 with one roll of a standard number cube?
The probability of rolling a seven with one roll of a standard number cube is zero.
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
What is the probability of rolling a 4 on each of 5 number cubes?
In a single roll for each die, it is (1/6)5 = 1/7776 = 0.000129 approx.
What are the chances of rolling a seven with 2 dices 2 times?
If they are normal cubes, the probability is 1, if you roll them often enough.
When you roll three number cubes what is the probability that all three numbers will match?
The probability is 1/36
When rolling 1 dice what is the probability of rolling number 4?
It is 1 (a certainty) if you roll it often enough. For a single roll of a fair die, the probability is 1/6.
When two number cubes are rolled what is the probability that their sum will be 3?
On a roll of two dice, the chance of rolling a 3 (one and two) is 2 in 36, or 1 in 18 when reduced.
If you roll a fair six sided number cube. What is the probability of rolling and eight?
The probability is 0.
