Week 4: 9/129/18 Statistics Chapter 5: Probability Sections: 14 Probability ● Probability of an event is the sum of the probabilities of the sample points in the sample space for the event ● If an event is impossible, the probability of the event is 0 and if an event is a certainty, the probability of the event is 1 ● Unusual event is an event that has a low probability of occurring ● The classical method of computing probabilities requires equally likely outcomes ● Two events are disjoint if they have no outcomes in common The General Addition Rule: P(E or F) = P(E) + P(F) P(E and F) ● The complement of any event (A) is the event that does not occur (A^C) ● Two events E and F are independent if the occurrence of event E in a probability experiment does not affect the probability of event F ● Two events are dependent if the occurrence of event E in a probability experiment affects the probability of event F Multiplication rule for independent events Compute atleast probability 1 P(A^C)
