My opinion is that it's fine to ask homework questions, people don't have to answer if they don't want to, and whether you get help is a matter between you and your professor. I do object to people who try to disguise homework questions, but only because they're so bad at it (the ones I notice, anyway). I also object to people typing in the entire problem and asking for the complete answer, I much prefer to help people who have narrowed it down but gotten stuck; or who don't know how to start.

However, it might make sense to post a pure probability question on a pure probability board. They'll most likely have an FAQ on common homework problems, or you can search to see if it's already been answered. If not, a hundred students may benefit from the answers you get.

On the other hand, a lot of people seem to come here looking for classroom help. Maybe this is as good a place as any.
