5369599837ProbabilityA number between 0 and 1 that reports the likelihood of the event's occurrence.0
5369599838TrialA single attempt1
5369599839OutcomeValue measured, observed, or reported for an individual instance of the trial2
5369599840EventA collection of outcomes3
5369599841IndependenceIf knowing whether one event occurs does not alter the probability that the other event occurs.4
5369599842Law of Large NumbersLong-run relative frequency of repeated independent events becomes close to actual frequency as number of trials increases.5
5369599843Complement Rule1 minus the probability that it doesn't occur6
5369599844Disjoint (Mutually Exclusive)They share no outcomes in common.7
5369599846General Addition RuleP(A U B) = P(A) + P(B) - P(A intersect B)8
5369599847Multiplication Rule of Independent EventsP(A intersect B) = P(A) * P(B)9
5369599848Sample SpaceThe collection of all possible outcome values10
5369599849Conditional ProbabilityP(B | A) = P(A intersect B)/P(A)11
5369599850Formal IndependenceP(B|A) = P(B)12
5369859882Disjoint (Mutually Exclusive) and independenceDisjoint events can't be independent because they have no outcomes in common-> knowing that one event occurred means that the other didn't.13
