Use the rules of probability to compute probabilities of compound events in a uniform probability model
Grade 912
S.CP.6.
Find the conditional probability of A given B as the fraction of B’s outcomes that also belong to A, and interpret the answer in terms of the model.
S.CP.7.
Apply the Addition Rule, P(A or B) = P(A) + P(B) – P(A and B), and interpret the answer in terms of the model.
S.CP.8.
(+) Apply the general Multiplication Rule in a uniform probability model, P(A and B) = P(A)P(BA) = P(B)P(AB), and interpret the answer in terms of the model.
S.CP.9.
(+) Use permutations and combinations to compute probabilities of compound events and solve problems.
