3 Notes Teacher Notes:  You need the sound on!  Photocopy sheet (double sided) and give one to each pair.  Ask them to choose a horse that they think will win.  You will need to run this for 20 to 30 minutes with a class of around 30 to get a decent set of results.  Enter results in the second row of table (editable)  Discuss the reasons for 7 winning (ask about opposite sides of a die).  Complete table of outcomes with students and relate distribution of results to table. (Ask some probability questions).

4 Game The Probability Race Game Finish Start Player 1: Player 2: Start Finish die 1 die Winning horse How to Play

5 Results Die 1 Die 2 Complete the table Did you know that the numbers on opposite faces of a die add to 7? P(7) = 6/36 = 1/6 We can use the table to calculate probabilities for other outcomes. Class Results

6 Die 1 Die 2 P(7) = 6/36 = 1/6 Calculate the probabilities of the following events. (a) P(5) (b) P(12) (c) P(even) (d) P(odd) (e) P(prime) (f) P(>4) (g) P(<9) (h) P(multiple of 3) = 4/36 = 1/36 = 18/36 = 15/36 = 30/36 = 26/36 = 12/36
