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
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
