Two (6-sided) dice roll probability table

Roll a… | Probability |
---|---|

7 | 21/36 (58.333%) |

8 | 26/36 (72.222%) |

9 | 30/36 (83.333%) |

10 | 33/36 (91.667%) |

## How many times can you roll a 9 with two dice?

This will be our denominator. How many ways can we get a 9 with two dice? 936 , which can be simplified to **14** .

## How many outcomes have a sum of at least 9?

(ii) two numbers appearing on them whose sum is 9. Therefore, total number of possible outcomes = **36**.

## How many different combinations of dice rolls produce a sum of 9 List the outcomes?

There is an equal probability of rolling each of the numbers 1-6.

…

What are the most likely outcomes from rolling a pair of dice?

Outcome | List of Combinations | Total |
---|---|---|

8 |
2+6, 3+5, 4+4, 5+3, 6+2 | 5 |

9 | 3+6, 4+5, 5+4, 6+3 | 4 |

10 | 4+6, 5+5, 6+4 | 3 |

11 | 5+6, 6+5 | 2 |

## 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 are the odds of rolling a 9 with two dice?

Probabilities for the two dice

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

6 | 5 | 13.89% |

7 | 6 | 16.67% |

8 | 5 | 13.89% |

9 | 4 |

## When two dice are thrown the total outcomes are?

Note that there are **36 possibilities** for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.

## What is the probability of getting a sum of at least 9?

❖ “At least one” is equivalent to “one or more.” 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 many ways can you roll a 9 with three dice?

So in total there are **25 ways** to get a sum of 9. If you want the probability, just take this over the total number of possibilities and you get 25/63=25/216.

## What is the probability of getting a sum greater than 9?

So probability of getting a sum greater than 9 is= 6/36=**1/6** Ans.
