Webb10 apr. 2024 · CDF of a random variable ‘X’ is a function which can be defined as, FX (x) = P (X ≤ x) (a) P (X = 3) To obtain the CDF of the given distribution, here we have to solve till the value is less than or equal to three. From the table, we can obtain the value F (3) = P (X 3) = P (X = 1) + P (X = 2) + P (X = 3)
