What is Meant by the Probability Density Function?

In probability and statistics, the probability density function is known as the probability function that describes the density of the continuous random variable that lies between a certain range of values. It is also known as the probability distribution function. The probability function will give a positive value at any point of a graph, and also the integral of the probability distribution function over the entire space should be equal to 1.
