COB 191 Chapter Notes - Chapter 4: Mutual Exclusivity, Contingency Table, Empirical Probability
Document Summary
Probability: chance, likelihood of speciic event occurring 0-1. Experiment: measuring and observing an acivity for purpose of collecing data. Sample space: all possible outcomes or results of experiment. Event: one or more outcomes of an experiment; subset of sample space. Simple event: an event with single outcome in its most basic form (ex: rolling a ive with a single die) Classical probability: number of possible outcomes of an event of interest is known; assumes that each event in sample space has same likelihood of occurring. Possible outcomes that constitute event a possible outcomes sample space total. Ex: rolling die p(a)= 1/6= . 167 simple probability: single event probability. Empirical probability: conducing experiment to observe frequency with which an event occurs. P ( a )= frequency which event a occurs observations total. Law of large numbers: when experiment is conducted a large number of imes; the empirical probability of the process will converge to the classical probabiliies.
