## 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**.

## What is the probability that the sum of two rolled dice is 9 given that at least one of the dice rolled is a 5?

So, there are only 2 combos that sum to 9 and have at least 1 of the die be a 4. So the probability is: (number of combos we want)/(total number of combos) = **2/36**.

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

Probabilities for the two dice

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

7 | 6 | 16.67% |

8 | 5 | 13.89% |

9 | 4 |
11.11% |

10 | 3 | 8.33% |

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

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)**.

## What is the probability of rolling two six sided dice with a sum of 9?

## What is the probability of getting a sum of 9 from throwing a pair of dice?

When 2 dice are thrown, the probability of the sum being 9 is **1/9**. When 2 cards are picked at random from a standard deck of cards, the probability of picking an ace and a queen is 8/663.

## 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 total of 5 or 9 or 11 when a pair of dice is rolled once?

If we want to calculate the probability of rolling, say, a five, we need to divide the number of ways to get 5 by the total possible combinations of two dice.
