Random Event
Random Event
in probability theory, an event that under given conditions may or may not occur and that has a certain probability p (0 ≤ p ≤ 1) of occurrence under the given conditions. A random event A can be seen to have a certain probability from the behavior of its frequency: if the indicated conditions occur n times, while A occurs precisely m times, then the frequency m/n will be close to p when n is large.
