If the drama club and the music club are combined, what percent of the combined membership will be male?

(1) Of the 16 members of the drama club, 15 are male;

(2) Of the 20 members of the drama club, 10 are male.

答案是E

实在搞不明白，‘Of the 16 members of the drama club’难道不是说drama club一共有16人吗？为什么答案不是C呢？

明天下午就要考了，这道题错的我一身冷汗那~~~~~

选E

of the 16 members of the drama club就是你说的意思，哪儿不明白了？

God,我的妈呀，又是一身冷汗哪~~

我就是用Percent=(15+10)/(16+20)选的C,快教教我呀，为啥选E呢？谢谢

If the drama club and the music club are combined, what percent of the combined membership will be male?

(1) Of the 16 members of the drama club, 15 are male;

(2) Of the 20 members of the drama club, 10 are male.

但是没有告诉 music club 的人数啊。所以，就不知道 the combined membership of drama club and music club. 没有办法给出概率的。

祝你好运。数学要仔细。一般时间还是够的。所以一定要仔细。

the problem made a mistake,it should be:

If the drama club and the music club are combined, what percent of the combined membership will be male?

(1) Of the 16 members of the drama club, 15 are male;

(2) Of the 20 members of the music club, 10 are male.

the answer is still the E.

同意楼上的，没说2个club的male是否有重复，仍然无法求解
