題目是 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? 這題答案是4/7 可以請大家幫我看一下這題題目嗎? 有點被搞混看不懂 我發現Q都錯在題目沒看仔細或是不懂 其實算式都很簡單 麻煩有空的人可以跟小弟講解一下 感激不盡 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.165.157.235
