SPAN 101 Chapter Notes - Chapter 7: Bernoulli Trial, Simple Random Sample, Unimodality
Document Summary
Law of large numbers: relative frequency of a random event settles down to a single number in the long run. Model based (theoretical) probability: empirical probability the relative frequency of an event"s occurrence as the, p(a) = # of outcomes in a / total # of outcomes probability of an event. Personal probability: personal assessment of an event expresses your uncertainty about the outcome, not based either on long run relative frequencies or equally likely events, satisfy the same rules as both empirical and theoretical probabilities. Rule 1: a probability is a number between 0 & 1. Rule 2: probability assignment rule: the probability of the set of all possible outcomes must be 1. Rule 3:the set of outcomes that are not in the event a is called complement of a, ac. Complement rule: the probability of an event occurring is 1 minus the probailtiy.
