Expert Solution
Step 1: Explain the basic information.

The question is about random variables.

Introduction :

Discrete random variable :

A random variable which takes whole no. or the data can be counted, known as discrete random variable.

Example : No. of mistakes in a page.

It will take values as 0, 1, 2,...,10


Continuous random variable :

A random variable which takes values in a continuous or interval form, known as continuous random variable.

Example : Height of the students in a class.

It will take values such as [ 150.5 cm, 170.5 cm ]


To find :

Identify the types of random variable for given parts.
