A Youtube video from ProfRobBob in which he goes over the General Addition and Multiplication Rules in Statistics. He shows how a Venn diagram can help with the General Addition Rule. He also explains how we started to learn conditional probabilities when we did row and column percents in 2 way tables.

Reason abstractly and quantitatively.

Model with mathematics.

Use appropriate tools strategically.

Attend to precision.

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.

(+) 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.
