* the [[Domain of a function|___domain]] is the set of possible [[Outcome (probability)|outcomes]] in a [[sample space]] (e.g. the set <math>\{H,T\}</math> which are the possible upper sides of a flipped coin heads <math>H</math> or tails <math>T</math> as the result from tossing a coin); and
* the [[Range of a function|range]] is a [[measurable space]] (e.g. corresponding to the ___domain above, the range might be the set <math>\{-1, 1\}</math> if say heads <math>H</math> mapped to -1 and <math>T</math> mapped to 1). Typically, the range of a random variable is
