The quality of lacking a pattern or organization so that result are unpredictable is also known as Randomness.
In the daily routine work, randomness can be defined as the apparent lack of pattern. Randomness occurs when there is no predictability in events. Thus a random pattern of events, steps or symbols often has no sequence and order so they lead eventually towards Randomness. Similarly when elements will not follow an intelligible pattern or a proper combination they will result in Randomness.
