※ 引述《jet96344 (爱恋狮子鱼)》之铭言:
: 题目是
: The odds that a certain event will occur is the
: ratio of the probability that the event will occur
: to the probability that it will not occur. If the
: odds that Pat will win a prize are 4 to 3, what is
: the probability that Pat will not win the prize?
我试试看...
某事件发生的机率适用比例来表示,发生的机率比上不发生的机率
Pat兄赢得奖品的机率是4比3,Pat兄不赢的机率是多少?
既然4:3赢的话..3就是输啦
所以机率应该是3/(4+3)=3/7
不知道各位高手小弟这样解有没有错误
