Explanation:

Detailed explanation-1: -Examples of discrete random variables include the number of children in a family, the Friday night attendance at a cinema, the number of patients in a doctorâ€™s surgery, the number of defective light bulbs in a box of ten.

Detailed explanation-2: -For example, if X is equal to the number of miles (to the nearest mile) you drive to work, then X is a discrete random variable. You count the miles. If X is the distance you drive to work, then you measure values of X and X is a continuous random variable.

Detailed explanation-3: -In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables.

Detailed explanation-4: -Discrete random variables can only take on a finite number of values. For example, the outcome of rolling a die is a discrete random variable, as it can only land on one of six possible numbers. Continuous random variables, on the other hand, can take on any value in a given interval.
