STAT 1100 Chapter Notes - Chapter 6: Cvent, Mutual Exclusivity, Sample Space
Document Summary
Section 1 assigning probability to events. 2/10/17: random experiment: an action or process that leads to one of several possible outcomes, first step in assigning probabilities is . List outcomes must be exhaustive: all possible outcomes must be included. Outcomes must be mutually exclusive: that no two outcomes occur at the same time. Sample space: of a random experiment is a list of all positive outcomes of the experiment. The outcomes must be exhaustive and mutually exclusive. Outcomes = o1, o2, . , ok: requirements of probabilities. Given a sample space s= {o1, o2, , ok}, the probabilities assigned to the outcomes must satisfy two requirements. The probability of any outcome must lie between o and 1: 0 p(o1) 1 for each i. The sum of the probabilities of all the outcomes in a sample space must be. Classical approach: used by mathematicians to help determine probability associated with games of chance: ex: flipping a coin, or rolling a die.
