Gr 12 (Probability)

1. Revise,

• the identity:  P(A or B) = P(A) + P(B)− P(A and B)

• the addition rule for mutually exclusive events: P(A or B) = P(A) + P(B)

• the complementary rule: P(not A) = 1− P(A)

• identifying dependent and independent events and,

• the product rule for independent events:  P(A and B) = P(A) ×P(B)

• the use of Venn diagrams to solve probability problems, for any three events.

• the use of tree diagrams for the probability of consecutive or simultaneous events

2. Apply the fundamental counting principle to solve probability problems

3. Probability problems using Venn diagrams, tree diagrams, two-way contingency tables and fundamental counting principle.
