我怎么觉得这个逻辑题应该选E呢？哪位NN来说一下？

以下是引用yaomao在2006-10-4 0:30:00的发言：

最後只好猜題目是要問拿business degree的有多少比例是講法文,
 

答案就该是50%

那应该是用条件概率了

A=business degree,B=french

求P(B/A)

P(B/A)=P(AB)/P(A)=20%/40%=50%

Hello, could someone please confirm also if the 50% is right

I dont understand what the question is asking.
