12.2.1 Reading
1. Difficult -
I don't understand the differences between De Morgan's laws... the shaded Venn Diagrams. I also do not understand what the "pairwise disjoint" is. I don't understand how Ai U Aj = 0 when i does not equal j...
2. Reflect -
I think I understand how we are going to use the property P(Ac) = 1 - P(A). If I remember correctly we will be using that for problems that ask something like "What is the probability that you will not choose a red ball?" (You'd have the information to find the probability of getting a red ball and then subtract that number from 1 to get the probability of not choosing a red ball.
