      The normal distribution is the only absolutely continuous distribution all of whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a given mean and variance. The normal distribution is a subclass of the elliptical distributions. The normal

The probability that a continuous random variable will assume a particular value is zero. As a result, a continuous probability distribution cannot be expressed in tabular form. Instead, an equation or formula is ...
