In this chapter we introduce the cumulative distribution function (cdf) of a random
variable X. The cdf is defined bya FX(x) := P(X≤x). As we shall see, knowing the
cdf is equivalent to knowing the density or pmf of a random variable. By this we ...

Introductory Econometrics: A Modern Approach
A random variable is one that takes on numerical values and has an outcome
that is determined by an experiment. In the coin-flipping example, the number of
heads appearing in 10 flips of a coin is an example of a random variable. Before
we ...

The random variable X, equal to the number of functional batteries in the sample,
is then said to be a hypergeometric random variable with parameters n, N, p. We
