Frequency/Total sample size
3. Classical..
Assumed equal likely outcome

Rolling Die

1/n ..n=#of outcomes
4. Subjective..
Based on opinion
5. Complement of an Event
The Complement of event A is defined to be the event consisting of all points that are not in A
6. Union of Two Events
The union of events A and B is the event containing all sample points that are in A or B or both

Usually a high probability
7. Intersection of Two Events
The intersection of events A and B is the set of all sample points that in both A AND B
P(A U B) = P(A) + P(B) - P(A n B)
9. Collectively Exhaustive
P(A) + P(B) = 1
