## Is rolling a dice discrete random variable?

A discrete random variable is a **random variable that can take on any value from a discrete set of values**. The set of possible values could be finite, such as in the case of rolling a six-sided die, where the values lie in the set {1,2,3,4,5,6}.

## Is dice a discrete variable?

Recall that a **discrete random variable** is one that can only take on one of a number of discrete values, and nothing in between. For example, a die (singular of “dice”) can come up 1, 2, 3, 4, 5 or 6, but not 1.5 or 2.3. … That’s a discrete random variable.

## Is rolling a dice a binomial distribution?

In other words, rolling a die twice to see if a 2 appears is a binomial experiment, because there is a fixed number of trials (2), and **each roll is independent of the others**.

## What are examples of discrete and continuous variables?

Difference between Discrete and Continuous Variable

Discrete Variable | Continuous Variable |
---|---|

Examples: Number of planets around the Sun Number of students in a class | Examples: Number of stars in the space Height or weight of the students in a particular class |

## What is an example of a continuous variable?

Continuous variables

A variable is said to be continuous if it can assume an infinite number of real values within a given interval. For instance, consider the height of a student. The height can’t take any values. … **The age** is another example of a continuous variable that is typically rounded down.

## What is the variance of rolling 2 dice?

Rolling one dice, results in a variance of 3512. Rolling two dice, should give a variance of **22Var(one die)=4×3512≈11.67**.
