S-CP.B.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.B.8. Apply the general Multiplication Rule in a uniform probability model, P(\mbox{$A$ and $B$}) = P(A)P(B|A) = P(B)P(A|B), and interpret the answer in terms of the model.
