随机
thumb|alt=|A Pseudorandom Number Generator|pseudorandomly generated [[bitmap]] In common usage, randomness is the apparent or actual lack of definite patterns or predictability in information. A random sequence of events, symbols or steps often has no order and does not follow an intelligible pattern or combination. Individual random events are, by definition, unpredictable, but if there is a known probability distribution, the frequency of different outcomes over repeated events (or "trials") is predictable. For example, when throwing two dice, the outcome of any particular roll is unpredicta
AI overview
Randomness describes when events or information appear to have no predictable pattern or order, even though individual outcomes cannot be foreseen. While we cannot predict what will happen in any single random event, we can predict how often different outcomes will occur over many repeated events if we know the underlying probabilities—like how rolling two dice will average certain results over time.

随机性（英語：Randomness）这个词是用来表达目的、动机、规则或一些非科学用法的可预测性的缺失。 一个随机的过程是一个不定因子不断产生的重复过程，但它可能遵循某个概率分布。 术语随机经常用于统计学中，表示一些定义清晰的、彻底的统计学属性，例如缺失偏差或者相關。随机与任意不同，因为“一个变量是随机的”表示这个变量遵循概率分布。而任意在另一方面又暗示了变量没有遵循可限定概率分布。 随机在自然科学和哲学上有着重要的地位。
