Synonym discussion
Sense: noun/1
All four words describe how likely something is, but they sit in different registers and structures. 'Chances' is the most everyday choice and accepts both 'good' and 'slim' easily, as in 'her chances of getting in are slim'. 'Odds' carries a faint betting flavour even outside gambling; speakers reach for it when the outcome feels uncertain or risky, as in 'the odds of finding survivors are low'. 'Likelihood' is more formal and usually singular, preferring abstract subjects: 'there is a strong likelihood of rain'. 'Probability' is the most technical, often used with an actual number: 'the probability is 0.35'. In short: chats and stories use 'chances'; risky or dramatic contexts use 'odds'; reports and essays use 'likelihood'; maths and science use 'probability'.

Etymology
The noun 'odds' grew out of the older adjective 'odd', which entered English from Old Norse 'oddi' meaning 'point of land' or 'triangle' — and, by extension, the third or extra item that could not be paired up. From the late 1500s, 'odds' (always plural) was used for the difference or imbalance between two things, especially the imbalance of advantage between two competitors. From this came both the modern senses: the general 'chance that something will happen' and the gambling 'ratio of payout to stake', where the bookmaker's numbers literally measure how unbalanced the contest is thought to be.
