What is PDF and CDF？

PDF stands for Probability Density Function, which is a function that describes the probability distribution of a continuous random variable. It is used to calculate the probability of a random variable taking a particular value within a range of values.

CDF stands for Cumulative Distribution Function, which is a function that describes the probability that a random variable takes a value less than or equal to a given value. It is used to calculate the probability of a random variable taking a value less than or equal to a certain value.
