## What is the probability of rolling a sum of 10 with two fair dice?

Probabilities for the two dice

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

10 | 3 |
8.33% |

11 | 2 | 5.56% |

12 | 1 | 2.78% |

Total | 36 | 100% |

## What is the probability of getting 0 sum of 10 on the two dice?

When you consider the sum being 10, there are only 3 combinations. So, the probability of getting a 10 would be 3/36 = **1/12**.

## What’s the probability of not rolling a sum of 7 with two dice?

Explanation: When rolling 2 dice there are 36 possible outcomes. [to see this imagine one die is red and the other green; there are 6 possible outcomes for the red die and for each of these red outcomes there are 6 possible green outcomes]. That is **30 out of 36 outcomes** will not be a 7 total.

## What is the probability of not rolling a sum of 4 with two fair dice?

Answer: The probability of rolling two dice and getting a sum of 4 is **1/12**. Let’s find how likely we get a sum of 4 when we roll two dice simultaneously. So, when we roll two dice there are 6 × 6 = 36 possibilities. When we roll two dice, the possibility of getting number 4 is (1, 3), (2, 2), and (3, 1).

## What is the probability of getting a sum of 7 with 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**.

## What is the formula of probability?

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.

6 | 5/36 (13.889%) |

7 | 6/36 (16.667%) |

## What is the probability of getting a number between 1 to 100 which is divisible by 7?

Favorable outcomes = **14** (because there are 14 numbers from 1 to 100 which are divisible by 7. i.e.,7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98.

## What is the probability of not rolling a sum of 9 on 2 dice?

The probability of getting 9 as the sum when 2 dice are thrown is **1/9**.

## What is the probability of not rolling a sum of 5 on two 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**.
