The Japanese noun '確率 (かくりつ)' means 'probability'. It refers to the likelihood or chance of an event occurring, often expressed numerically or as a percentage. This term is commonly used in mathematics, statistics, and everyday conversations when discussing uncertain outcomes. For example: the probability of rain is high「雨の確率が高い」(あめのかくりつがたかい). What is the probability of winning?「勝つ確率はどれくらいですか?」(かつのかくりつはどれくらいですか?). It can also be used in contexts like gambling or risk assessment, such as 'the probability of success is low'「成功する確率は低い」(せいこうするかくりつはひくい).
