For instance, while flipping a coin, the value i. PDF Probability Density Function is the likelihood of the random variable in the range of discrete value.
On the other hand, PMF Probability Mass Function is the likelihood of the random variable in the range of continuous values. On the other hand, a probability density function PDF , or density of a continuous random variable, is a function that describes the relative likelihood for this random variable to take on a given value. A probability mass function differs from a probability density function pdf in that the latter is associated with continuous rather than discrete random variables; the values of the latter are not probabilities as such: a pdf must be integrated over an interval to yield a probability.
PDF, on the other hand, is used when you need to come up with a range of continuous random variables. PDF uses continuous random variables. CDF is used to determine the probability wherein a continuous random variable would occur within any measurable subset of a certain range.
