CHAPTER 2 Random Variables and Probability Distributions 35 EXAMPLE 2.2 Find the probability function corresponding to the random variable X of Example 2.1.
To determine the distribution of a discrete random variable we can either provide its PMF or CDF. For continuous random variables, the CDF is well-defined so we can

Definition. The probability density function ("p.d.f. ") of a continuous random variable X with support S is an integrable function f(x) satisfying the following:
