            Lesson 68:

            FYI...When an experiment occurs in stages, we can use a tree
                diagram to help us find the sample space and the number
                of outcomes


                     First coin   Second coin   Third coin   Outcomes

                     SO...the Multiplication Rule for Probability is:

                         ***If events A and B are independent, then
                             P(A and B) = P(A) x P(B)
