I think my stat theory professor put some shitty questions on the midterm though. We were asked to prove pic related, but we explicitly skipped the chapters on multivariate distributions (in fact, the prof said we wouldn't even touch multivariate distributions until the second semester stat theory course). I posted this in /sqt/, but I got a stupid response. Should I ask the prof about this? Or should I have been able to solve it.

This drives me mad.
On a side note, do you think it's fair to ask students to prove this theorem on an exam if the chapters on multivariate distributions were not assigned?
