comment First and Follow Sets for a Grammar
For D, if E = epsilon, then F becomes the First of D. The First of F = {x,epsilon}. Since we already have epsilon from E then we just add x to the First set of D, making it {y,x,epsilon} from what I can remember. I did this for an exam ages ago and I think this was how the lecturer taught it anyway.

Thanks for the confirmation on it being correct. I think I've figured it out but I'm in the same boat as you, can't really explain it. I id my exam and it seemed to go well anyway!
