* Probability distributions. In probability theory, a probability mass,
* probability density, or probability distribution is a function that
* describes the probability of a random variable taking certain values.
*
* In the discrete case, one can easily assign a probability to each possible
* value. In contrast, when a random variable takes values from a continuum,
* probabilities are nonzero only if they refer to finite intervals.
*
* If total order is defined for the random variable, the cumulative
* distribution function gives the probability that the random variable
* is not larger than a given value; it is the integral of the non-cumulative
* distribution.
