If you want to know how likely it is to get a certain total score from rolling two or more dice, it’s best to fall back on the simple rule: Probability = Number of desired outcomes ÷ Number of possible outcomes.

## What is the probability of rolling one dice?

Two (6-sided) dice roll probability table. Single die roll probability tables.

…

Probability of rolling more than a certain number (e.g. roll more than a 5).

Roll more than a… | Probability |
---|---|

1 | 5/6(83.33%) |

2 | 4/6 (66.67%) |

3 | 3/6 (50%) |

4 | 4/6 (66.667%) |

## 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 2 dice?

Probabilities for the two dice

3 | 2 | 5.56% |

4 | 3 | 8.33% |

5 | 4 | 11.11% |

## What is the probability formula?

P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.

## What is a dice formula?

Probability = **Number of desired outcomes ÷ Number of possible** outcomes = 3 ÷ 36 = 0.0833. The percentage comes out to be 8.33 per cent. Also, 7 is the most likely result for two dice. Moreover, there are six ways to achieve it. The probability in this case is 6 ÷ 36 = 0.167 = 16.7 percent.

## What is the most common number to roll with 1 dice?

You can see, only number **7** can be scored in each case, therefore 7 is the most common result, if you roll one dice and then another one.

## What is the probability of getting a total of 7 when rolling 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**.
