how likely something is
How likely it is that something will happen.
Vzorec užití:
the probability of [something] / the probability that [clause]
Častá chyba:
Learners often say *"the probability to happen"* instead of *"the probability of [something] happening"* or *"the probability that [something] will happen"*. They also sometimes confuse *probability* with *possibility*: *possibility* only means something can happen, while *probability* talks about how likely it is.
Synonyma
likelihood (Very close in meaning and register; common in both everyday and formal use.)
|
chance (More informal and flexible; often used in conversation instead of 'probability'.)
|
odds (Informal and often used when comparing how likely something is, especially in speech and gambling contexts.)
Antonyma
impossibility (Emphasizes that something cannot happen at all, corresponding to zero probability.)
|
certainty (Emphasizes that something will definitely happen, corresponding to maximum probability.)

mathematical measure of likelihood
In math and statistics, a number that shows how likely an event is, usually between 0 and 1 or 0% and 100%.
Vzorec užití:
the probability that [clause] is [number] / the probability of [event] is [number]
Častá chyba:
Learners may confuse the general idea of *probability* with the exact numerical value used in statistics. In technical contexts, *probability* often needs a number (e.g., 0.25), not just 'high' or 'low'. They may also incorrectly say *"0.5 of probability"* instead of *"a probability of 0.5"*.
Synonyma
statistical likelihood (Highlights that the likelihood is expressed in numerical, statistical terms.)
|
probability value (Technical term for the actual number representing probability.)
Antonyma
impossibility (Represents a probability of 0, meaning the event cannot occur.)
|
certainty (Represents a probability of 1 (or 100%), meaning the event must occur.)

likely event or outcome
One possible result or situation that you think about together with how likely it is.
Vzorec užití:
a/an [adjective] probability that [clause] / consider all the probabilities
Častá chyba:
Learners sometimes use *possibilities* when speakers would prefer *probabilities* to stress how likely each outcome is. They may also overuse the uncountable form and avoid the countable plural, saying *"think about probability"* instead of *"think about all the probabilities"* when comparing different possible outcomes.
Synonyma
possibility (Focuses more on something that can happen; *probability* implies stronger thinking about how likely it is.)
|
prospect (Often used for future events, especially in business or personal life, and can carry emotional or evaluative meaning.)
Antonyma
certainty (Opposes the idea of several possible outcomes by suggesting only one definite outcome.)
