MAT 156: StatisticsAny collection of results or outcomes of a procedure - ANS-Event
# of Favorable Outcomes/# of Total Outcomes - ANS-P(A)=
The "complement" of A = probability of event A not occuring - ANS-P(Ā)=
P(A)=7/10 - ANS-If P(Ā) = 3/10 then
Fraction or 3 significant figures - ANS-Round off rule
Number of favorable outcomes : Number of not favorable outcomes - ANS-Odds
The more times an experiment is repeated, the closer the experimental probability will be to the
theoretical probability. - ANS-Law of Large Numbers
A procedure is a process that behaves in the same way as the procedure itself so that similar
results are produced - ANS-Simulation
disjoint - ANS-Late or early to next stats class
Disjoint - ANS-Getting a job at Whitney's or North Scott Foods
P(A or B) = P(A) + P(B) - ANS-Disjoint Addition Rule
P(A or B) = P(A) + P(B) - P(A and B) - ANS-Not disjoint addition rule
Any event combining two or more simple events - ANS-Compound Event
Events for which the occurrence of one does not affect the probability of the other -
ANS-Indepedent events
Events for which the occurence of one does affect the probability of the other - ANS-Dependent
Events
P(A) x P(B|A) - ANS-P(A and B)
Probability of event B "GIVEN" event A has already occured. - ANS-P(B|A)
P(A) + P(Ā) = 1 - ANS-Complement Formula
