Critiquing Assignment - Junyuan Zheng

Thanks for the feedback! I get what you mean about the Probabilities and Factors section; but I'm not sure a full reorganization is necessary. I've put in links to make sure people know about the worked example, and I've added some text to more clearly motivate that the purpose of the math is to allow us to calculate probabilities; we'll see during the grading if those measures are adequate.
