Answer 2

A variable whose value is obtained by counting data is called a discrete random variable.

• A discrete variable involves only a finite number of values that are countable.
• So, a variable whose value is obtained by counting data is called the discrete variable.
• The examples of a discrete variable are marks obtained in a test, number of accidents per year, number of students in the class, the amount of money a person has, etc.
• In the above examples, all things are countable and finite.
• We can express discrete variables in the form of magnitude or numeric.
• We can measure the discrete variables using specific measures.

Hence, a variable whose value is obtained by counting data is called a discrete random variable.
