Meanings

Noun

  1. the quality of happening by chance or without a clear pattern or plan

  2. the statistical or algorithmic property of being unpredictable or patternless

Beyond the definition

Randomness is the state of having no clear order or pattern. Think of rolling dice or flipping a coin: you cannot know for sure what will happen next. It describes things that happen by chance rather than by plan. People often believe they see patterns even when there are none, so this idea can be harder to notice than it seems. It appears in games, statistics, science, and many parts of daily life.
