• Summary: Discover the meaning of jīlǜ (几率), the common Chinese word for “probability,” “chance,” or “likelihood.” This page breaks down how to use jīlǜ in everyday conversations about everything from weather forecasts to winning the lottery. Learn its cultural nuances and see how it differs from the more formal term 概率 (gàilǜ) and the concept of “opportunity,” 机会 (jīhuì), making your Mandarin more precise and natural.

• Pinyin (with tone marks): jīlǜ
• Part of Speech: Noun
• HSK Level: HSK 5
• Concise Definition: The mathematical or perceived likelihood of an event occurring; probability or chance.
• In a Nutshell: 几率 (jīlǜ) is your go-to word for talking about “chance” or “probability” in most daily situations. Think of it as the general feeling or estimate of how likely something is to happen. While it can be used for statistics, it's much more common in casual chats about the chances of rain, the likelihood of a team winning, or the probability of bumping into an old friend. It's less about strict formulas and more about practical, everyday possibility.

• 几 (jī): While this character often means “how many?” or “a few,” in this context it carries a sense of *potential* or *possibility*. It asks “what are the chances?” or “what is the potential number/amount?”
• 率 (lǜ): This character clearly means “rate,” “ratio,” or “proportion.” It’s used in many words related to statistics and measurement, like `效率 (xiàolǜ)` for “efficiency.”
• Combined Meaning: When you put them together, 几率 (jīlǜ) literally translates to the “rate of potential” or “ratio of possibility,” which perfectly captures the modern meaning of “probability” or “chance.”

While 几率 (jīlǜ) is a modern, scientific-sounding word, it operates within a culture that has long-standing ideas about fate and luck. Traditionally, Chinese culture has strong concepts of `命运 (mìngyùn)` (fate/destiny) and `运气 (yùnqì)` (luck). These concepts suggest that life's outcomes are influenced by a combination of a pre-determined path and a mysterious, fluctuating force of fortune. 几率 (jīlǜ) introduces a more modern, Westernized way of looking at uncertainty. It's objective and quantifiable. You can contrast these ideas:

• 命运 (mìngyùn): “It is my destiny to fail this exam.” (Fatalistic, unchangeable)
• 运气 (yùnqì): “I have bad luck, so I will probably fail this exam.” (Attributed to an external, mystical force)
• 几率 (jīlǜ): “Because I didn't study, the 几率 of me passing is very low.” (Rational, cause-and-effect)

In modern China, these concepts coexist. Someone might rationally discuss the 几率 of a business succeeding while also visiting a temple to pray for good 运气. This blending of rational calculation and traditional belief is a fascinating aspect of contemporary Chinese society.

几率 (jīlǜ) is a versatile word used in many contexts, mostly neutral in tone. Its formality depends on the situation.

• Informal/Everyday Conversations: This is where 几率 shines. It's the most common way to talk about chance.
  • Discussing the weather: “今天下雨的几率很大。” (The chance of rain today is high.)
  • Talking about games or lotteries: “中彩票的几率太小了。” (The chance of winning the lottery is too small.)
  • Making guesses: “我们碰巧遇到的几率是多少啊？” (What's the probability of us meeting by chance?)
• Semi-Formal/Business Contexts: In meetings or reports, 几率 is perfectly acceptable for discussing the likelihood of outcomes.
  • “这个项目成功的几率有多高？” (What is the probability of this project's success?)
  • “我们必须评估失败的几率。” (We must evaluate the probability of failure.)
• Formal/Academic Contexts: In highly technical, mathematical, or scientific writing, the term 概率 (gàilǜ) is often preferred as it sounds more precise and academic. However, in a spoken presentation about the same topic, a scientist might still use 几率 to sound more accessible.

• Example 1:
  • 根据天气预报，明天下午下雨的几率是百分之八十。
  • Pinyin: Gēnjù tiānqì yùbào, míngtiān xiàwǔ xià yǔ de jīlǜ shì bǎifēnzhī bāshí.
  • English: According to the weather forecast, the probability of rain tomorrow afternoon is 80 percent.
  • Analysis: A very common and straightforward use of 几率 for expressing a statistical likelihood in an everyday context.
• Example 2:
  • 虽然手术有风险，但医生说成功的几率很高。
  • Pinyin: Suīrán shǒushù yǒu fēngxiǎn, dàn yīshēng shuō chénggōng de jīlǜ hěn gāo.
  • English: Although the surgery has risks, the doctor said the chance of success is very high.
  • Analysis: Here, 几率 is used to convey hope and manage expectations in a serious situation.
• Example 3:
  • 你觉得我们这次赢得比赛的几率大吗？
  • Pinyin: Nǐ juédé wǒmen zhè cì yíngdé bǐsài de jīlǜ dà ma?
  • English: Do you think our chances of winning the game this time are high?
  • Analysis: The adjective `大 (dà)` (big) is often used with 几率 to mean “high probability,” while `小 (xiǎo)` (small) means “low probability.”
• Example 4:
  • 在这么大的城市里，两个人能偶然相遇的几率微乎其微。
  • Pinyin: Zài zhème dà de chéngshì lǐ, liǎng gè rén néng ǒurán xiāngyù de jīlǜ wēihūqíwēi.
  • English: In such a big city, the chance of two people meeting by accident is minuscule.
  • Analysis: `微乎其微 (wēihūqíwēi)` is an idiom meaning “extremely small” or “negligible,” used here to emphasize the low probability.
• Example 5:
  • 如果你现在开始努力，通过考试的几率会大大增加。
  • Pinyin: Rúguǒ nǐ xiànzài kāishǐ nǔlì, tōngguò kǎoshì de jīlǜ huì dàdà zēngjiā.
  • English: If you start working hard now, the probability of you passing the exam will greatly increase.
  • Analysis: This sentence shows how actions can affect 几率. It's not just about passive chance, but about influencing outcomes.
• Example 6:
  • 投资股票时，你必须计算盈利和亏损的几率。
  • Pinyin: Tóuzī gǔpiào shí, nǐ bìxū jìsuàn yínglì hé kuīsǔn de jīlǜ.

• Example 8:
  • 哪种方法的成功几率更高一些？
  • Pinyin: Nǎ zhǒng fāngfǎ de chénggōng jīlǜ gèng gāo yīxiē?
  • English: Which method has a higher probability of success?
  • Analysis: A practical question used for decision-making by comparing probabilities.
• Example 9:
  • 从统计学上讲，这种事情发生的几率几乎为零。
  • Pinyin: Cóng tǒngjìxué shàng jiǎng, zhè zhǒng shìqíng fāshēng de jīlǜ jīhū wéi líng.
  • English: Statistically speaking, the probability of this kind of thing happening is almost zero.
  • Analysis: This shows 几率 being used in a slightly more formal, data-oriented context, bordering on the territory of `概率 (gàilǜ)`.
• Example 10:
  • 为了增加被录取的几率，他申请了十所大学。
  • Pinyin: Wèile zēngjiā bèi lùqǔ de jīlǜ, tā shēnqǐngle shí suǒ dàxué.
  • English: In order to increase his chances of being accepted, he applied to ten universities.
  • Analysis: A perfect example of taking action to actively improve one's probability of a favorable outcome.

The most common point of confusion for learners is distinguishing 几率 from two similar-sounding words: `概率 (gàilǜ)` and `机会 (jīhuì)`.

• 几率 (jīlǜ) vs. 概率 (gàilǜ):
  • `几率` is “probability” or “chance” in a general, everyday sense. It's more common in spoken language.
  • `概率` is “probability” in a strict, mathematical, or scientific sense. It's more formal and written.
  • Think of it this way: You discuss the `几率` of your favorite team winning. A statistician calculates the `概率` of that win based on historical data. They are often interchangeable, but using `概率` in a very casual chat might sound a bit stiff.
• 几率 (jīlǜ) vs. 机会 (jīhuì): This is a crucial difference.
  • `几率` is a *measurement* of likelihood (a rate, a percentage).
  • `机会 (jīhuì)` is an *opportunity* or a *chance to do something*.
  • Incorrect: 我有一个好几率去中国工作。(I have a good probability to work in China.)
  • Correct: 我有一个好机会去中国工作。(I have a good opportunity to work in China.)
  • Correct: 我能得到这个工作机会的几率很高。(The probability of me getting this job opportunity is high.)

• 概率 (gàilǜ) - The formal, mathematical term for “probability.” It is the more technical synonym of 几率.
• 机会 (jīhuì) - An opportunity; a chance to act. This is what you get, whereas 几率 is the likelihood of you getting it.
• 可能性 (kěnéng xìng) - Possibility; the state or fact of being possible. It focuses on *whether* something can happen, while 几率 focuses on *how likely* it is to happen.
• 运气 (yùnqì) - Luck; fortune. This is the unquantifiable, mystical force that influences outcomes, whereas 几率 is a rational measure of chance.
• 命运 (mìngyùn) - Fate; destiny. The idea that outcomes are predetermined, which is a philosophical contrast to the random or statistical nature of 几率.
• 风险 (fēngxiǎn) - Risk. This term specifically refers to the 几率 of a negative or undesirable outcome.
• 偶然 (ǒurán) - Accidental(ly); by chance. An adjective or adverb describing an event that happened without a plan, often one with a low 几率.
