Question

Using the spinner below – if spun twice in a row – theoretically how many outcomes would involve at least one purple (2)?

a circle with three sections, labelled 1, 2, 3

Answer 1

There are 9 total possible combinations. 11,12,13,21,31,22,33,23,32. Five involve purple.



The answer is 5

Answer 2

Explanation:

Draw a 3 part Venn diagram as shown in the picture and then add up all the ones in the purple circle as that symbolises how many times a spinner can land there:

1+1+1

= 3
