- 1/ˌprɑːbəˈbɪləti/ · /ˌprɒbəˈbɪləti/機率、可能性
Probability is how likely something is to happen — how much of a chance there is. In math class, probability is often written as a number or percentage, like 'there's a 50% probability of rain.' In everyday talk, people use it more loosely, like 'in all probability, he'll be late,' meaning 'he's very likely to be late.'
