## What is the probability of not getting a sum of 8 if a pair of dice is rolled?

The probability of any number occurring is 1 in 36 or 1 / 36. Then the probability an 8 will not occur is: **1 – 5 / 36 or 31 / 36**.

## What is the probability that the sum is 8 when throwing a dice given that the first die shows a 3?

The total number of ways to roll an 8 with 3 dice is therefore 21, and the probability of rolling an 8 is **21/216**, which is less than 5/36.

## What is the probability of getting a total of 8 in a single throw of two dice?

There are 5 dice rolls that have a total sum of 8. (2,6) (3,5) (4,4) (5,3) (6,2). So the probability of getting a sum of 8 is 5/36 or **approximately 13.89%**.

## What is the probability of rolling a pair of dice and getting a sum of two?

## When two dice are rolled what is the probability that the sum is either 7 or 11?

2 Answers. The probability is **25%** .

## What is the probability of getting a sum 8?

So the probability of the event of showing the sum of the numbers on the face equal to 8 is **5/36**. We can get 8 when both the dice have 4, or when either has 6 and the other has 2 or when either has 5 and the other has 3.

## What is the probability of rolling one die and getting a 7?

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**.

## What is the probability of getting a sum 7 from two throws of dice?

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**.

## What is the probability of getting a prime number when a dice is tossed?

Answer: When a dice is thrown once, the probability of getting a prime number is **1/2**.
