A spinner with nine equal sections numbered 1 to 9 is spun. A is the event ‘the spinner lands on an odd number’ and B is the event ‘the spinner lands on a number greater than 6’. The outcomes of this experiment and events A and B are shown in the Venn diagram.
(a) Use the diagram to list the elements in each of the following sets: (i)
A
(ii) A’ (iii) a number greater than 6 (iv) a number greater than 6, which is not odd (v) ( A\B )′ (vi) Is A∪B = B∪A? Justify your answer with supporting work. (vii) Is A\B = B\A ? Justify your answer with supporting work.
(b) Based on the Venn diagram provided, calculate the probability that the spinner will land on a number that is less than 6 and even.
(c) Explain in words what the following set notation describes, and list the elements contained in each.
