AP Statistics Probability Review
Questions And Answers | Solved
Probability CORRECT ANSWERS A number between 0 and 1 that reports the likelihood
of the event's occurrence.
Trial CORRECT ANSWERS A single attempt
Outcome CORRECT ANSWERS Value measured, observed, or reported for an
individual instance of the trial
complement of A CORRECT ANSWERS 1-P(A)
Independence CORRECT ANSWERS If knowing whether one event occurs does not
alter the probability that the other event occurs.
Law of Large Numbers CORRECT ANSWERS Long-run relative frequency of repeated
independent events becomes close to actual frequency as number of trials increases.
Disjoint (Mutually Exclusive) CORRECT ANSWERS They share no outcomes in
common.
General Addition Rule (not mutually exclusive) CORRECT ANSWERS P(A U B) = P(A)
+ P(B) - P(A intersect B)
Multiplication Rule of Independent Events CORRECT ANSWERS P(A) * P(B)
Sample Space CORRECT ANSWERS The collection of all possible outcome values
Conditional Probability CORRECT ANSWERS P(B | A) = P(A intersect B)/P(A)
Law of Averages CORRECT ANSWERS A flawed way of thinking that if an event
doesn't happen for a while that it is due to occur soon.
General Addition Rule (mutually exclusive events) CORRECT ANSWERS P(A U B) =
P(A) + P(B)
Multiplication rule of dependent events CORRECT ANSWERS P(A|B)*P(B) = P(A
intersect B)
Probability Distribution CORRECT ANSWERS Lists all possible outcomes of a random
event and each outcome's probabilities
disjoint CORRECT ANSWERS aka mutually exclusive
