Multiplication Rule for Probability




 


Videos and lessons to help High School students learn how to 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.

  • Define the probability of event (A and B) as the probability of the intersection of events A and B.
  • Understand P(B|A) to mean the probability of event B occurring when A has already occurred.
  • Use the multiplication rule, P(A and B) = P(A)P(B|A) = P(B)P(A|B), to determine P(A and B).
  • Determine the probability of dependent and independent events in real contexts
