I have a question on my Maths homework that I am not sure about. I've tried working it out but I just can't get an answer.
Question: Eight soccer teams play each other once during a tournament. Two points are awarded for a win, one for each draw and zero for each loss. How many points must a team score to be sure that it will finish in the top four? [The team must finish with more points than at least four other teams]
If someone could help me with this question, it would be much appreciated. If you show the answer, please explain how you worked it out.
Thank you
