'''Probability''' is a way of expressing [[knowledge]] or [[belief]] that an event will occur or has occurred. In [[mathematics]] the [[concept]] has been given an exact meaning in probability theory, that is used extensively in such areas of study as mathematics, [[statistics]], [[finance]], gambling, science, and philosophy to draw conclusions about the likelihood of [[potential]] [[events]] and the underlying [[mechanics]] of [[complex]] [[systems]].
