LEARNING INTENTIONS:
SUCCESS CRITERIA: I can use a Venn diagram.e.g. A survey of 30 people in 2019 found that 12 thought Nick Kyrgios would win a grand slam tennis event in his career and 16 thought Alex De Minaur would win a grand slam tennis event in his career. Of those, 6 thought both would win a grand slam event while 8 thought neither would win one. Construct a Venn diagram. Use this to state how many people do not think Nick Kyrgios will win one as well as the probability that a randomly chosen person thinks only Alex De Minaur will win one. I can use a two-way table.e.g. On a particular day at a car service station, 20 cars are serviced: 12 cars need a wheel alignment, 10 cars need their brake fluid replaced and 4 require both. Illustrate the situation using a two-way table. Use the table to find how many cars require neither, and the probability that a randomly selected car needs only a wheel alignment.
