WebDec 27, 2024 · 1 Answer. The .cdf () function calculates the probability for a given normal distribution value, while the .ppf () function calculates the normal distribution value for which a given probability is the required value. These are inverse of each other in this particular sense. To illustrate this calculation, check the below sample code. Webbinom takes n and p as shape parameters.
