Introduction

Probability density function is used to represent the continuous variable. Probability mass function used to represent the discrete variable. It is used to represent the chance of observation outcome of discrete random variable. It follow two conditions, they are all the probability value greater than 0 and the sum of all the probability value is equal to 1.
