WebYou'll first want to note that the probability mass function, f ( x), of a discrete random variable X is distinguished from the cumulative probability distribution, F ( x), of a discrete random variable X by the use of a lowercase f and an uppercase F. That is, the notation f (3) means P ( X = 3), while the notation F ( 3) means P ( X ≤ 3). WebDec 1, 2024 · Probability mass and density functions are used to describe discrete and continuous probability distributions, respectively. This allows us to determine the probability of an observation being exactly equal to a target value (discrete) or within a set range around our target value (continuous). popcorn 66 game
