High School Statistics and Probability
Domain Conditional Probability and the Rules of Probability
Cluster Understand independence and conditional probability and use them to interpret data
Standard Understand the conditional probability of $A$ given $B$ as \(P(\mbox{$A$ and $B$})/P(B)\), and interpret independence of $A$ and $B$ as saying that the conditional probability of $A$ given $B$ is the same as the probability of $A$, and the conditional probability of $B$ given $A$ is the same as the probability of $B$.

S-CP.A.3. Understand the conditional probability of $A$ given $B$ as \(P(\mbox{$A$ and $B$})/P(B)\), and interpret independence of $A$ and $B$ as saying that the conditional probability of $A$ given $B$ is the same as the probability of $A$, and the conditional probability of $B$ given $A$ is the same as the probability of $B$.
