Document Summary

Sample space: the set of all possible outcomes (s). Null space (null set): a space or set that has 0 probability of the event occuring. Probability distribution: a function that describes the probability of a random variable taking certain values. The union of two events a and b , denoted by a b, is the set of all elementary outcomes that are in a, b, or both. The occurrence of a b means that either a or b or both occur. A b (event a or event b occur) De nition: the intersection of two events a and b, denoted bya b, is the set of all elementary outcomes that are in a and b. The occurrence of a b means that both a and b occur. A b (event a and event b occur) A b (event a is subset of events of event b) Probability experiment: any action for which an outcome cannot be predicted with certainty.
