CA II.2 Probability and Integral Functions

I still think it's important to take the time to do the little modeling problem in the midst of this probability introduction activity. I stressed that this is how appropriate probability models are developed - by modeling observed data.

Synthesis questions probably need to be given some significant class time as there is not much pulling together of the concepts discovered at the end of this activity. Although, I did add one graphical class discussion question at the end.
