Customer Question

I am going to take...

I am going to take an exam where I will be tested in three areas; and in each area, I will be given two questions and I can select the one I want to answer. In each area, there are nine possible questions. In studying for the exam, I am considering preparing answers to four questions in each area, five questions in each are or six questions in each area. My questions are these: If I prepare four questions in each area, what are my chances of having one question answered in advance? What are my chances of having two questions already answered? What are my chances of having three questions answered?

If I prepare answers for five of the nine questions, what are my chances of having one, two or three questions answered?

If I prepare answers for six of the nine questions, what are my chances of having one, two or three questions already answered?

I don't have the math skills to calculate this question. If you can help me, I would appreciate it. Thanks, Ken
