1. Difficult - It is difficult to find anything to say because this section is pretty straight forward. I will note something interesting though, I never really knew probability and statistics were intertwined. (Like in High School they seem very separate. Most likely because the mathematics isn't high enough yet to explain how they connect.)... I think I can tell by the prob. function graphs and the norm. dist graphs that those are what are used in probability.

Oh the subk notations are to denote each RV right x1, x2, x3 (when used in Ex 1 and 2 in the summations)
2. Reflective - I think I have seen the S sub n notation before in stat's class for variance... I think.
