WebOct 30, 2024 · The CDF of a random variable X X is a function that represents the probability that X X will be less than or equal to x x. The function is defined as F X(x) = P (X ≤ x) F X ( x) = P ( X ≤ x). Using the table generated while creating the PMF one can calculate the value of F X(x) F X ( x) by summing all associated probabilities for possible ...
