| Total | Number of combinations | Probability |
|---|---|---|
| 3 | 2 | 5.56% |

What is the probability of getting a 5 on a die?
If a die is rolled there are 6 possible outcomes—1,2,3,4,5,6. So the probability of getting a 5 is 1/6.
When throwing 2 dice What is the probability of rolling a sum of 5 on the first roll and a sum of 7 on the second roll?
Probability corresponding with sum 5 is 436 and probability corresponding with sum 7 is 636. Neglecting the other outcomes we find a probability 410 for sum 5 and 610 for sum 7.
What is the probability of rolling a 1 on a die?
Explanation: The probability of rolling at least one “1” if you roll a dice six times is the same as 1 minus the probability of rolling zero 1s if you roll a dice six times. The probability of not rolling a 1 if you roll a dice once is 5/6.
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%
What is the probability of getting a total of 7 when rolling 2 dice?

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.
