## How many times can you roll a 7 with 2 dice?

When two dices are rolled, there are **six possibilities** of rolling a sum of 7 .

## What is the probability of rolling a total of 7 with two dice at least once in 10 rolls?

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. This implies that we will get a total of 7 on at least one of the first 10 rolls 100%−16.15%=**83.85%** of the time.

## What is the ratio of rolling a 2 to rolling a 5?

Two (6-sided) dice roll probability table

Roll a… | Probability |
---|---|

2 | 1/36 (2.778%) |

3 | 2/36 (5.556%) |

4 | 3/36 (8.333%) |

5 | 4/36 (11.111%) |

## What are the outcomes of rolling 2 dice?

Note that there are **36 possibilities for (a,b)**. This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.

## What is the probability of rolling a sum of 7 or 11 with two fair dice?

What is the probability of rolling a sum of 7 or 11 with two dice? So, P(sum of 7 or 11) = **2/9**.
