Random variable formula_12 formula_13. In some contexts, the term "random element" (see Extensions) is used to denote a random variable not of this form. When the image (or range) of formula_5 is finite or countably infinite, the random variable is called a discrete random variable and its distribution can be described by a probability mass function which assigns a probability to each value in the image of formula_5. If the image is uncountably infinite then formula_5 is called a continuous random variable. In the special case that it is absolutely continuous, its distribution can be described by a probability density function, which
