Definition in Chinese

表示某一事件发生的可能性或倾向，既可通过理论计算得到，也可由经验频率估计，常以小数或百分比表示。biǎo shì mǒu yí shì jiàn fā shēng de kě néng xìng huò qīng xiàng jì kě tōng guò lǐ lùn jì suàn dé dào yě kě yóu jīng yàn pín lǜ gū jì cháng yǐ xiǎo shù huò bǎi fēn bǐ biǎo shì

Word origin

概 (gài, "rough estimate") + 率 (lǜ, "rate") form a compound that treats an event's chance as a proportion rather than a simple yes-or-no judgment.

Usage tips

  • English often uses "chance" in casual contexts, but probability is also natural when a decimal or percentage is involved, separating a general guess from a quantified estimate.
