1. Yes.
2. Have you been studying at all for this? You should know answers to questions like this and the other one on which topics will be on the exam at this point ... if you're having to ask now, :QuestionMark:

hm...thank you Irish Blues. However, I've only seen gamma mix Poissons and normal mix normal on the old exams...and I can't find these in the textbook. Would you be kind enough to tell me what other types I need to memorize? I'd really appreciate it.
