## What is the sum of a 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 + ….

## How many ways can 2 dice fall?

How many total combinations are possible from rolling two dice? Since each die has 6 values, there are 6∗6=**36** 6 ∗ 6 = 36 total combinations we could get. If you add up the numbers in the total column above, you’ll get 36.

## How do you calculate total outcomes?

Once again, the Counting Principle requires that you take the number of choices or outcomes for two **independent events and multiply them together**. The product of these outcomes will give you the total number of outcomes for each event.

## How many possible outcomes are there?

The total number of possible outcomes are **6**, 3 ∙ 2 = 6. This principle is called the fundamental counting principle and the rule is as follows. If event x (in this case the chicken, the beef and the vegetables) can occur in x ways.

## What is the average dice roll?

The average dice roll of 2d6 will be **7**. This becomes faster as you memorize the average dice roll of a singular die. If you know that the average roll of 1d6 is 3.5 you’ll just skip to multiplying your average by the number of dice you’re rolling in the future.

## What is opposite 4 on a dice?

In both the positions, face number 1 is common for both dice is same. Therefore, the opposite of 4 is **2** and the opposite of 5 is 6.
