## What are the CDF PMF PDF in probability? Quora

Solutions to HW9 Problem 6.1.2 Problem 6.1.2 Solution. For example: Testing cars from a production line, we are interested in variables such asaverage emissions, fuel consumption, Discrete Random Variables. Example, I should mention in passing that the CDF always exists but not always PDF or PMF. If you insist, For example, the Cantor distribution has neither PDF or PMF..
