| probability density function |
In mathematics, a probability density function (pdf) serves to represent a probability distribution in terms of integrals. Any function that is everywhere non-negative and whose integral from −∞ to +∞ is equal to 1 is a probability density function. If a probability distribution has density f(x), then intuitively the infinitesimal interval [x, x + dx] has probability f(x) dx. ...

The word probability derives from the Latin probare (to prove, or to test). Informally, probable is one of several words applied to uncertain events or knowledge, being more or less interchangeable with likely, risky, hazardous, uncertain, and doubtful, depending on the context.Chance, odds, and bet are other words expressing similar notions. ...

| probability distribution |
A probability distribution Pr{} on a sample space S is a mapping from events of S to real numbers such that the following probability axioms are satisfied: Pr ≥ 0 for any event A. Pr = 1. Pr{A ∪ B} = Pr + Pr for any two mutually exclusive events A and B. (See page 1101)
