There are 6 identical number pairs. That means there are 6 chances out of 36 possibilities to get a pair of numbers as the outcome. Thus, the p(a pair when two fair dice are rolled) = 6/36 = 1/6. You can use the normal table format or the method below.
What is the probability of rolling two dice and getting different numbers?
8 Answers. The probability of rolling a specific number twice in a row is indeed 1/36, because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6). The probability of rolling any number twice in a row is 1/6, because there are six ways to roll a specific number twice in a row (6 x 1/36).
What is the probability of rolling a two total with two dice?

What is the probability of rolling a 2 on a 6 sided die?
Probability of rolling a certain number or less for two 6-sided dice.
Two (6-sided) dice roll probability table.
What is the probability of getting a 7 when rolling 2 dice?
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
What is the probability of rolling a 7 or 11 with two dice?
What about 7 OR 11? There are 6 x 6 or 36 options, all are equally likely, 7 occurs 6 times, so the chances are 6/36 or 1/6. 11 occurs 2 times so chances are 2/36 or 1/18. 7 or 11 are 8 of the 36 options so 8/36 or 2/9.
When two sided dice are rolled There are 36 possible outcomes?
Every time you add an additional die, the number of possible outcomes is multiplied by 6: 2 dice 36, 3 dice 36*6 = 216 possible outcomes.
What is the formula for calculating probability?
How to calculate probability
- Determine a single event with a single outcome.
- Identify the total number of outcomes that can occur.
- Divide the number of events by the number of possible outcomes.
How do you find the probability of 3 dice?
We divide the total number of ways to obtain each sum by the total number of outcomes in the sample space, or 216. The results are: Probability of a sum of 3: 1/216 = 0.5% Probability of a sum of 4: 3/216 = 1.4%
