问题单项选择题

An analyst gathers the following information about the odds of two companies raising new stock.

If the companies' actions are independent, the probability that both companies will issue debt is closest to.（）

A. 0.136

B. 0.171

C. 0.343

答案

参考答案：A

解析：

几率(odds)等于事情发生的可能性除以事情不发生的可能性，P₁=3/(3+5)=0.3750，P₂= 4/(4+7)=0.3636，所以两个独立事情一起发生的概率为P₁×P₂=0.3750×0.3636=0.136。
