## What is the probability of rolling at least one 4?

Probability of rolling a certain number or less with one die

Roll a…or less | Probability |
---|---|

3 | 3/6 (50.000%) |

4 | 4/6 (66.667%) |

5 | 5/6 (83.333%) |

6 | 6/6 (100%) |

## How do you find the probability of at least?

To find the probability of at least one of something, calculate **the probability of none and then subtract that result from 1**. That is, P(at least one) = 1 – P(none).

## How do you find the probability of two dice?

If you want to know how likely it is to get a certain total score from rolling two or more dice, it’s best to fall back on the simple rule: **Probability = Number of desired outcomes ÷ Number of possible outcomes.**

## What is the probability of rolling a sum of 2 with two dice?

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 that you threw 7 and at least one of the dices is a six?

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**.
