2.   Theoretical: true mathematical probability  Empirical: the relative frequency with which an event occurs in a given experiment  Subjective: an educated guess Types of Probability

3.   Experiment: any process that yields a result or observation  Outcome: a particular result of an experiment  Sample Space: the collection of all possible outcomes  Event: any collection of outcomes; any subset of the sample space  Example: Roll die  Let A={1}  Let B={2, 4, 6}  Let C={3, 6}  An event occurs if any outcome of the event occurs Review Terms

4.   P(A) = # of outcomes/# outcomes in sample space  If each outcome is equally likely  Using previous slide’s events:  P(A)=  P(B)=  P(C)= Probability of Event
