Shame on you for asking such a transparent question.
Which is it?

Have you no idea of a possible solution?
If not, then you are in real trouble; the kind of trouble that no website such as this can possibility address

3. Yeh i'm in trouble. frankly, I do have no idea about this whole pigeon hole concept and implication. will you help me?

gender(male | female) is as pigeonhole? and the students are as pigeons?
So that in order to get 9 student out of it, we have to get at least 5 male and 5 female students?

So, after all, you DO HAVE some idea, uh? Well, now think on it and, if you feel adventurous, open a book or some web site and learn even more about the very famous Pigeonhole Principle.
