Conditional Probability (and Probability) P(B|A) = P(A and B)/P(A) or P(A|B) = P(A and B)/P(B) Determining Independence P(B|A) = P(B) or P(A and B) = P(A) x P(B) can be used. Multiplication Rule for Independent Events If two events are independent, then P(A and B) = P(A) x P(B). Disjoint Two events which cannot both occur at the same time. Theoretical Probability Formula Probability of Event = # of outcomes in the event / Total # of outcomes in the sa...
