Assumed equal likely outcome Rolling Die 1/n ..n=#of outcomes Subjective.. Based on opinion Complement of an Event The Complement of event A is defined to be the event consisting of all points that are not in A 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 Intersection of Two Events The intersection of events A and B is the set of all sample points that in both A AND B Addition Law P(A U B) = P(A) + P(B) - P(A n B) Collectively Exhaustive P(A) + P(B) = 1 A random variable- a NUMERICAL description of the outcome of an experiment Discrete- how many Continuous- how much Catergorical data is always..?
