AP Statistics Probability Flashcards

7617866435	Probability	A number between 0 and 1 that reports the likelihood of the event's occurrence.	0
7617866436	Trial	A single attempt	1
7617866437	Outcome	Value measured, observed, or reported for an individual instance of the trial	2
7617866438	complement of A	1-P(A)	3
7617866439	Independence	If knowing whether one event occurs does not alter the probability that the other event occurs.	4
7617866440	Law of Large Numbers	Long-run relative frequency of repeated independent events becomes close to actual frequency as number of trials increases.	5
7617866442	Disjoint (Mutually Exclusive)	They share no outcomes in common.	6
7617866443	General Addition Rule (not mutually exclusive)	P(A U B) = P(A) + P(B) - P(A intersect B)	7
7617866444	Multiplication Rule of Independent Events	P(A) * P(B)	8
7617866445	Sample Space	The collection of all possible outcome values	9
7617866446	Conditional Probability	P(B \| A) = P(A intersect B)/P(A)	10
7617866447	Law of Averages	A flawed way of thinking that if an event doesn't happen for a while that it is due to occur soon.	11
7617907522	reverse conditioning (baye's rule)	P(A\|B) = P(B\|A)*P(A)/P(B)	12
7617929465	General Addition Rule (mutually exclusive events)	P(A U B) = P(A) + P(B)	13
7617936758	Multiplication rule of dependent events	P(A\|B)*P(B) = P(A intersect B)	14
7618004528	Probability Distribution	Lists all possible outcomes of a random event and each outcome's probabilities	15
7618014226	disjoint	aka mutually exclusive	16
7618020833	P(at least 1)	1-P(none)	17
7618041795	venn diagram	a helpful diagram to draw when you have events that are not mutually exclusive.	18
7618081150	Two Way Table	A table that lists counts for 2 categorical variables that is helpful with conditional probabilities.	19
7618103830	P(A\|B)	Probability of event A given that event B occurs.	20
