Document Summary
If an experiment has n possible outcomes, this method would assign a probability of 1/n to each outcome. It is necessary to determine the number of possible outcomes. Relative frequency approach: find the relative frequency of an event occurring through experiementation. Interpreting probabilty: no matter which method is used to assign probabilities all will be interpreted in the relative frequency approach. Joint, marginal, conditional probability: we study methods to determine probabilities of events that result from combining other events in various ways, there are several types of combinations and relationships between events, compment event. Intersection of events: union of events, mutually exclusive events, dependent and independent events. Complement of an event: the compliment of an event is defined to be the event consisting of all sample points that are not in a , complement of a is denoted by ac, p(a) + p(ac) = 1.
