## How many times would you expect to roll a 5?

There are six sides on a die. Five is one option out of six. If the cube is fair, then the probability of having “5” as one side is 1/6. Given that tossing dice are independent each other events, you may have “5” nearly 3000/6= **500 times**.

## How do you find the expected value of a dice?

The expected value of the random variable is (in some sense) its average value. 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 mean of a dice roll?

The mean is the type of average most people are used to. To find the mean **for a set of numbers, add the numbers together and divide by the number of numbers in the set**. For example, if you roll two dice thirteen times and get 9, 4, 7, 6, 11, 9, 10, 7, 9, 7, 11, 5, and 4, add the numbers to produce a sum of 99.

## What is the most common number to roll with 1 dice?

, and the least common rolls are 2 and 12, both with probability 1/36. For three six-sided dice, the most common rolls are **10 and 11**, both with probability 1/8; and the least common rolls are 3 and 18, both with probability 1/216.

## How do you calculate the probability of a dice?

Think about a dice. When a dice is rolled there are 6 possible outcomes: 1, 2, 3, 4, 5 and 6. To find the probability of the event of rolling a 4, find the number of possible ways of rolling a 4 **and divide it by the total number of possible outcomes**.

## What is the probability of rolling a 4?

Two (6-sided) dice roll probability table

Roll a… | Probability |
---|---|

4 | 3/36 (8.333%) |

5 | 4/36 (11.111%) |

6 | 5/36 (13.889%) |

7 | 6/36 (16.667%) |

## How many times will you get a six if you throw a dice 100 times?

About 9 **times** it **will take** 4 **throws**(36 **throws**) etc. Then **you would** add up ALL of those **throws** and divide by **100** and **get** ≈**6**.
