probability
word
Definition
The measure of how likely it is that a certain event will happen, usually expressed as a number between 0 (impossible) and 1 (certain).
Usage & Nuances
Mainly used in mathematics, statistics, science, and daily speech to express chance. Often followed by 'of': 'the probability of rain'. Not interchangeable with 'possibility'—'probability' suggests calculation or a specific chance, while 'possibility' just means something can happen.
