Question

Which of the following random variables is geometric?

Answer 1

Answer:

b. The number of digits in a randomly selected row until a 3 is found.

Explanation:

A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.

In statistics and probability, random variables are either continuous or discrete.

1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.

2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.

Also, any random variable that meets certain conditions defined in a research study.

Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.
