Maths homework help - Probability.

[--ski--]

Girlfriends brother is staying with us, he needs help. I said I would help him. I can't. Can anybody please help me establish superiority and dominance over my future brother in-law by helping me pretend I'm intelligent? Thanks.

If anybody has any answers, please post them. I will be gratetful. Thanks.
