how likely something is

How likely it is that something will happen.

الگوی کاربرد: the probability of [something] / the probability that [clause]
اشتباه رایج:
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.
هم‌معنی‌ها
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.)
متضادها
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%.

الگوی کاربرد: the probability that [clause] is [number] / the probability of [event] is [number]
اشتباه رایج:
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"*.
هم‌معنی‌ها
statistical likelihood (Highlights that the likelihood is expressed in numerical, statistical terms.) | probability value (Technical term for the actual number representing probability.)
متضادها
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.

الگوی کاربرد: a/an [adjective] probability that [clause] / consider all the probabilities
اشتباه رایج:
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.
هم‌معنی‌ها
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.)
متضادها
certainty (Opposes the idea of several possible outcomes by suggesting only one definite outcome.)
