Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = 1/9.

## What is the probability of rolling a sum of 5 with a pair of dice?

Probabilities for the two dice

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

4 | 3 | 8.33% |

5 | 4 | 11.11% |

6 | 5 |
13.89% |

7 | 6 | 16.67% |

## When rolling two dice What is the probability of rolling a sum of 5 given at least one die shows a 1?

The Event that the some of dots is five and one of the die shows “one”. Out of those 11 possibilities, two sum to 5 ([1,4] and [4,1]), so the probability is **2/11**.

## What is the probability distribution of getting a sum of 5?

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% |

## 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 not rolling a sum of 5?

1 Expert Answer

The rolls that add to five are 1-4, 2-3, 3-2, and 4-1 so there are 4 rolls that add to five. That means there are **32 rolls** that do not add to five (because there are 36 total possible rolls).

## What is the probability of not rolling a sum of 5 with two fair dice?

To find the probability determine the number of successful outcomes divided by the number of possible outcomes overall. Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = **1/9**.

## What is the probability of getting a sum of 20 when tossing 2 dice?

Answer Expert Verified

The maximum sum that we can get when we roll 2 dice is 12. So, the probability of getting 20 is obviously .

## What is the probability of getting a 2 or a 5 when a die is rolled?

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 is the probability that the sum are 5 and 7?

That’s not exactly right because the true probability is that MINUS the probability of getting both a sum of 5 and a sum of 7. In other words, the answer = p(sum of 5) + p(sum of 7) – p(sum of 5 and sum of 7) , which equals p(1–4, 4–1, 2–3, 3–2) + p(1–6, 6–1, 2–5, 5–2, 3–4, 4–3) – 0 = **10/36** or 5/18.

## What is the probability of rolling a sum less than 10?

That totals 8 combination out of 36 that could be ten or higher, so 8/36= 2/9. since I wanted less than ten 1-(2/9) = **7/9** probability of getting less than 10.
