1 Determining Probabilities Using Tree Diagrams and Tables

2 Probability The likelihood or chance of an event occurring Often shown as a fraction, decimal, or percent A tree-diagram or table can be used to show the possible outcomes Independent events The outcome of one event has no effect on the outcome of the other event – Coin and spinner

3 Tree Diagram Example on the board Sample Space – All possible outcomes of a probability experiment Probability (P) = # of favourable outcomes total # of possible outcomes

4 Table See examples on board

5 Assignment Pg 416 – 417 # 3 – 10
