Webb28 dec. 2024 · A probability mass function, often abbreviated PMF, tells us the probability that a discrete random variable takes on a certain value. For example, suppose we roll a dice one time. If we let x denote the number that the dice lands on, then the probability that the x is equal to different values can be described as follows: P (X=1): 1/6. P (X=2 ...
