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).

P(7) = 6/36 = 1/6 We can use the table to calculate probabilities for other outcomes. Class Results
