## What is the probability of getting a sum of 7 with two 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 sum math?

noun. **the aggregate of two or more numbers, magnitudes, quantities, or particulars** as determined by or as if by the mathematical process of addition: The sum of 6 and 8 is 14.

## What is the probability that the sum of the dice is not 7?

With the help of a calculator we find that we will not get a total of 7 on any of the first 10 rolls approximately **16.15%** of the time.

## What is the probability of rolling a 7 or 8?

Roll a… | Probability |
---|---|

6 | 15/36 (41.667%) |

7 | 21/36 (58.333%) |

8 | 26/36 (72.222%) |

9 | 30/36 (83.333%) |

## What is the probability that you obtain a sum of 7 or a sum of 11 on the first roll?

For example, since a 7 or an 11 is a winner on the first roll and their probabilities are 6/36 and 2/36, the probability of winning on the first roll is 6/36+2/36=**8/36**.
