Probability of a sum of 15: 10/216 = 4.6%

## How many ways can a sum of 15 be obtained with 3 dice?

It is by finding non-negative integral solutions to the following equation. Therefore, the number of ways in which the sum of the numbers observed in 3 rolls of fair dice is 15 is equal to **10**.

## What is the probability of getting a sum of 15 when two dice are thrown?

So, the number of favourable outcomes =1+2+4+6+2=15. We know that the number of possible outcomes is 36. Thus, the probability of getting the sum of two numbers as prime numbers is =**1536=512**. (b) We will now calculate the probability of occurrence of a doublet of an even number.

## What is the probability of getting a sum of 12 when rolling 3 dice simultaneously?

## What is the probability that the sum is less than or equal to 9 in three rolls of a die?

1+2+6 in any order (there are 3!= 6 ways to arrange 3 different objects.) Out of 216 possible outcomes, **25** of them sum to 9. There are 6^3 = 216 possible outcomes after fair rolling of 3 fair dies.

## What is the probability of getting 1 and 5 If a dice is thrown once?

So they are mutually exclusive events, therefore their probabilities add to 1. By symmetry we expect that each face is equally likely to appear and so each has probability = **1/6**. The outcome of a 5 is one of those events and so has probability = 1/6 of appearing.

## What is the probability of all possible outcomes?

The sum of the **probabilities of all outcomes must equal 1** . If two events have no outcomes in common, the probability that one or the other occurs is the sum of their individual probabilities.

## What will be the probability of getting odd numbers if a dice is thrown?

probability of getting odd nos. =63 =**21**.
