## What is the probability of rolling 2 dice and getting less than 4?

Probability of rolling a certain number or less for two 6-sided dice.

…

Two (6-sided) dice roll probability table.

Roll a… | Probability |
---|---|

4 | 6/36 (16.667%) |

5 | 10/36 (27.778%) |

6 | 15/36 (41.667%) |

7 | 21/36 (58.333%) |

## When two dice are rolled find the probability of getting a sum less than or equal to 5?

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 rolling a sum less than or equal to 6?

There are: 6×6=36 possible outcomes. Of these there are **10** totals which are less than 6 .

## What is the probability of rolling a sum less than or equal to 7?

We can express this a couple of ways: P(sum of 2 number cubes≤7)=2136=**712**. P(sum of 2 number cubes≤7)=1−P(sum of 2 number cubes>7)=1−1536=2136=712.

## What is the probability of getting a sum of 7 when rolling two 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% |

## 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.
