HSS.CP.B.8

**HSS.CP.B.8**: (+) Apply the general Multiplication Rule in a uniform probability model, P(A and B) = P(A)P(B|A) = P(B)P(A|B), and interpret the answer in terms of the model.

HSS.CP.B.8: (+) Apply the general Multiplication Rule in a uniform probability model, P(A and B) = P(A)P(B|A) = P(B)P(A|B), and interpret the answer in terms of the model.

What you'll learn

State the general Multiplication Rule, P(A and B) = P(A) * P(B | A) = P(B) * P(A | B)
Apply the rule to compute joint probabilities for dependent events, such as draws without replacement
Use tree diagrams to organize sequential events, multiplying conditional probabilities along branches
Recognize the independence special case, where P(B | A) = P(B) reduces the rule to P(A) * P(B)
Interpret a computed joint probability in terms of the model and its context
