If the range of random variables is a discrete set it is called discrete random variable. Usually described by it’s Probability Mass Function (PMF). PMF = Random Variable X set on Range T Fₓ(t) : T -> [0,1] is defined as Fₓ(t)= P(X=t) for t ∈ T X=t is the event P(X=t) is probability of X taking the
