What students learn

Find all combinations for two events using two-way tables, tree diagrams and Venn diagrams, and use them to work out probabilities.

Worked example
A fair coin is flipped and a fair six-sided die is rolled. What is the probability of getting tails AND rolling a 5? Write your answer as a fraction.
Answer: 1/12
Why: P(tails) x P(rolling 5) = 1/2 x 1/6 = 1/12
