Synonym discussion
Sense: noun/1
Chance is the most general and informal word, used in everyday conversation about uncertain outcomes ('a chance of rain'). Likelihood is slightly more formal and neutral, common in data-driven or analytical writing ('the likelihood of success is high'). Probability carries a mathematical or scientific tone, used when uncertainty can be measured ('the probability of rolling a six is one in six'). Prospect often implies a future outcome that is hoped for or expected, giving it a slightly more positive feel ('a job prospect'). While possibility simply says something is not impossible, probability suggests it is more likely than not. In everyday speech, chance and possibility are often interchangeable, but probability and likelihood belong to more careful or technical contexts.

Etymology
Possibility comes from the Latin word 'possibilitas', which was formed from 'posse' meaning 'to be able'. It entered English through Old French 'possibilité' in the 14th century. The '-ity' suffix turns the adjective 'possible' into a noun, giving English a word that has expressed the idea of uncertain outcomes for more than 600 years.
