Giving a total of 21 different number combinations (out of 216 possible combinations) which sum to 8. So there are (21)/(216) possible correct combinations which meet the demands of the question. This gives a probability of (21)/(216) or 9.72222% or 0.097222 of getting a sum of 8 when 3 die are thrown.

## What is the probability that rolls don’t match?

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).

## What is the probability of rolling three?

Two (6-sided) dice roll probability table

Roll a… | Probability |
---|---|

3 | 3/36 (8.333%) |

4 | 6/36 (16.667%) |

5 | 10/36 (27.778%) |

6 | 15/36 (41.667%) |

## What are the odds of rolling 3 dice the same number?

The probability of getting the same number is **1/6**. Throw the third die. The probability of getting the same number is again 1/6. So the probability of three numbers the same is 1/6×1/6.

## How do you find the probability of rolling 3 dice?

Probability for rolling three dice with the six sided dots such as 1, 2, 3, 4, 5 and 6 dots in each (three) dies. When three dice are thrown simultaneously/randomly, thus number of event can be **6 ^{3} = (6 × 6 × 6) = 216** because each die has 1 to 6 number on its faces.

## What is the probability of getting an even number when rolling a single 6 sided die?

The probability of rolling an even number on a six sided die is **3/6**, or 1/2.

## What is the probability of rolling a sum of 4?

Probabilities for the two dice

Total | Number of combinations | Probability |
---|---|---|

2 | 1 | 2.78% |

3 | 2 | 5.56% |

4 | 3 |
8.33% |

5 | 4 | 11.11% |

## What is the probability of getting 1 and 5 If a dice is thrown once?

So they are mutually exclusive events, therefore their probabilities add to 1. By symmetry we expect that each face is equally likely to appear and so each has probability = **1/6**. The outcome of a 5 is one of those events and so has probability = 1/6 of appearing.

## What is the probability of getting a sum of 7 when two dice are thrown?

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**.
