這兩個詞是客觀的可能性,可以表示有可能,也可以表示沒可能,比如:
The likelihood of getting the disease is very high.
The probability of getting 100 points is very low.
possibility 是有可能的意思
there is a possibility that something will happen.
註意,如果把上面的句子改成:
there is a probability that something will happen.
意思就由原來的某事可能發生,變成某事很可能發生。
也就是說probability有兩種用法,壹個和likelihood壹樣,表示概率;壹個比possbility意思相似但程度更深,表示很可能
