Conditional Probabilities - Tree Diagrams

In class students reviewed how to use Venn diagrams and contingency tables to find probabilities.  Afterwards, students learned that when given a conditional probability, one should use a tree diagram to find other probabilities.

Things to Remember.

            1.  "Replacement" or "Without Replacement?"
            2.   Use Venn or Contingency table when given basic probabilities.
            3.   Use tree diagram when given conditional probabilities.
            4.  Be familiar with formulas but use graphic organizers to answer questions.
            5.  "At least one" or "some" means...1 - none.
            6.  Define/differentiate disjoint/mutually exclusive and independent...and prove
                 independence P (A|B) = P(A)
