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 on 2 dice?

## 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.

## How many ways can get sum of 5 when you roll two dice at the same time?

We can get a sum of 5 in **two different combinations** also: (1,4) and (2,3).

## When rolling two dice What is the probability that you roll a sum of 5 or a sum that is a prime number?

15 out of 36 of the outcomes are a prime number sum. So that is the probability …. 15/36 = **5/12**.

## 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 rolling a 5 or 7?

Two (6-sided) dice roll probability table

Roll a… | Probability |
---|---|

4 | 3/36 (8.333%) |

5 | 4/36 (11.111%) |

6 | 5/36 (13.889%) |

7 | 6/36 (16.667%) |

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

The only way to get a sum of 5 is to get three 1’s and one 2. So there are 4 ways to get that 2 with the other three 1’s, and a sum of 5. There are 6 ways each die can land so there are 6^4 or1296 ways for the dice to land. So the probability is **5/1296**.
