Repost this. But next time tell us: 1. What is the question you are trying to answer? 2. What is it about this question that is giving you difficulty? 3. What work have you done, successful or otherwise, to try to solve the problem on your own?
If this is too much trouble for you, then helping you at all is too much trouble for us.
