random numberA number selected without any criteria, often by some sort of generator, such as a computer program.

We will choose a raffle winner at random.See also: randomat randomby chance; haphazard. The lottery numbers are chosen at random. As a prank, the children dialed phone numbers at random.See also: randomat randomWithout order or fixed purpose, haphazardly, as in Jackson Pollock dropped paints on canvas seemingly at random. Originally this phrase meant "very speedily" and "heedlessly." Shakespeare had the present usage in 1 Henry VI (5:3): "He talks at random; sure the man is mad." [Late 1500s] See also: random at random Without a governing design, method, or purpose; unsystematically: chose a card at random from the deck.See also: randomrandom

random [ran´dum] pertaining to a chance-dependent process.ran·dom (ran'dŏm), 1. Governed by chance; used of a process in which the outcome is indeterminate but may assume any of a set of values (the domain) with probabilities specifiable in advance. Although the random process is widely used in probability theory, empiric justification for the term is more complicated. The minimum requirement is that repeated realization of the process will settle down to a stable distribution or, if not metric, a stable set of frequencies if the trait is classifiable only. 2. [M.E. randon, speed, errancy, fr. O. Fr. randir, to run, fr. Germanic] random Occurring by chance alone–ie, not by design, pattern, plan, or selection Clinical trials Referring to a formal chance process in which previous events have no bearing on future events. See Random allocation, Randomized trial. ran·dom (ran'dŏm) Governed by chance; denotes a process in which outcome is indeterminate. [M.E. randon, speed, errancy, fr. O. Fr. randir, to run, fr.
