This is for a practice test I received in my stochastic processes class. The teacher is incredibly difficult and won't answer questions, he just says to refer to the notes we have, which are just as hard to understand as this. If anyone can point me in the right direction on any part I would really appreciate it.
There are 4 questions, so I will make an individual post for each of them.

Sorry for joining just to post these questions, but I have looked for help in multiple places, and I have received none.
