Is rolling two dice discrete or continuous?

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.
