## When 2 dice is rolled what is the probability that the sum of the numbers is 13?

Explanation: If we’re talking about standard number cubes, then the maximum answer possible is 12 (=6+6) . Therefore, all possible rolls are less than 13, giving a probability of **100%**.

## When two dice are rolled what is the probability that the sum?

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.

## 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.

## What is the probability of getting a prime number from 1 to 100?

The prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. Hence, the probability of the event that a number chosen from 1 to 100 is a prime number .

## What is the probability the sum of two rolled dice is 12?

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 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.

## What is the probability of getting the sum of 6?

Probability of getting a total of 6 = **5/36**.

## What is the probability of getting a 4?

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%) |
