I had Hunter work on 10 questions from a "Math For College Readiness" final exam review sheet. He was able to complete some of the exercises easily, while others required my assistance.
I introduced "probability of multiple events". We tallied how may odd and prime numbers we got after rolling 2 die. We talked about independent and dependent events, and used P(A and B) = P(A)*P(B). Mutually exclusive events are 2 events that cannot happen at the same time. We used different formulas to find the probability of (A or B). I showed him Khan Academy videos that taught some basics of probability.
