Check list:

  1. Revise and use tree diagrams and Venn diagrams to solve probability problems.
  2. The use of tree diagrams for the probability of consecutive or simultaneous events which are not necessarily independent.
  3. Revise the addition rule for mutually exclusive events: P(A or B) = P(A) + P(B).
    The complementary rule: P(not A) = 1 - P(A). 
    And the identity P(A or B) = P(A) + P(B) - P(A and B).
  4. Dependent and independent events and the product rule for independent events: P(A and B) = P(A) x P(B).

Learn the concepts:

There is a lot of terminology and notation that you need to know how to use correctly to succeed in this section. Take careful notes while going through these videos, and make sure that you will understand them when you use them as study notes later in the year. I find it easier to understand the rules if I apply them to a Venn diagram.
