## What is the probability that the sum of the two dice is even?

First, the probability of rolling an even number: You can either have an odd number on each die, or an even number on each die. There is a 1/2 probability of rolling either an odd or even number, so both probabilities are 1/2 x 1/2 + 1/4, and adding those together gives **a 1/2 probability** of rolling any even number.

## What is the probability of both dice being even?

I’m fairly certain that the probability of both dice returning an even number is **1/4**. I got this by saying that since these are independent events, with each die returning an even number being 1/2, then the probability of both being even is 1/2×1/2=1/4.

## What is the probability of rolling two even numbers with two dice?

P(E)=636=16. Probability of two different even numbers = Probability of both even * Probability of both different given they are both even. Probability of both even is **12×12=14**.

## How many even sums are possible with 2 dice?

There are 36 outcomes from 2 dice. **18** are odd, 18 are even. This can be confirmed by counting the even outcomes in the array above. In addition to the 18 even numbers there are 2 odd numbers less than 5: 3 and 3.

## What is the sum of two dice?

You compute it by multiplying each value x of the random variable by the probability P(X=x), and then adding up the results. So the average sum of dice is: **E(X) = 2 ^{.} 1/36 + 3**

^{.}2/36 + ….

## What is the probability of rolling an even number on a dice?

The probability of rolling an even number is **three out of six**, or three-sixths. This fraction can be simplified as the numerator and denominator are both divisible by three. Three divided by three is equal to one, and six divided by three is equal to two. This means that the answer, in its simplest form, is one-half.

## What is the probability of rolling two six sided dice and obtaining an even number on both dice?

Three out of the six sides of a die are even numbers, so there is a 3/6 probability of rolling an even number on each of the dice. The chance of having an even number on both dice is (3/6)(3/6) = **9/36**, or ¼.
