probability that something will occur
How likely it is that something will happen.
用法模式：
the likelihood of [something] / the likelihood that [clause]
常见错误：
Learners often say *"the likelihood to do something"* instead of the more natural *"the likelihood of doing something"* or *"the likelihood that something will happen"*. They may also confuse "likelihood" with "possibility"; "likelihood" suggests thinking about how probable something is, not just whether it can happen at all.
近义词
probability (More formal and slightly more common in statistics and technical contexts, but often interchangeable.)
|
chance (More informal and general; sounds less technical than "likelihood".)
反义词
improbability (Direct opposite, focusing on the fact that something is not likely to happen.)
|
impossibility (Stronger opposite, meaning there is no chance at all that something will happen.)
搭配
high likelihood
|strong likelihood
|reduce the likelihood
|likelihood of success
|likelihood that

statistical likelihood function
In statistics, a number or function that shows how well some values in a model fit the data you see.
用法模式：
the likelihood of [parameters] given [data]
常见错误：
Learners often think this technical sense is exactly the same as everyday "probability". In statistics, likelihood is a function of model parameters given fixed data, while probability is usually a function of data given fixed parameters.
近义词
likelihood function (More explicit technical term; refers specifically to the function, not just the general idea of probability.)
反义词
loss function (Not a direct semantic opposite, but often conceptually contrasted in modeling, where one is maximized and the other minimized.)
