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

Contents

## 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 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.

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

Outcome Probability
8 5/36 = 13.89%
9 4/36 = 11.11%
10 3/36 = 8.33%
11 2/36 = 5.56%
