Seminar 1 published

Proposed solutions to seminar 1 are now published. Sorry if my notes sometimes are a bit messy, but I think it should be readable (ask me if you are uncertain about something).

At first I just assumed E[XY]=0 in the exercise with variance, but this cannot be known to be true in general. But the clue is to remember that E[XY] is less then or equal sqrt(VarX)*sqrt(VarY), where sqrt denotes the square root.
