3 Discrete Random Variables and Probability Distributions

3 Discrete Random Variables and Probability Distributions Stat 4570/5570 Based on Devore s book (Ed 8) 2 Random Variables We can associate each single outcome of an experiment with a real number: We refer to the outcomes of such experiments as a Random variable . Why is it called a Random variable ? 3 Random Variables Definition For a given sample space S of some experiment, a Random variable ( ) is a rule that associates a number with each outcome in the sample space S. In mathematical language, a Random variable is a function whose domain is the sample space and whose range is the set of real numbers: So, for any event s, we have X(s)=x is a real number.

The Cumulative Distribution Function Definition The cumulative distribution function (cdf) denoted F(x) of a discrete r.v. X with pmf p(x) is defined for every real number x by F(x)= P(X ≤ x) = For any number x, the cdf F(x) is the probability that …
