We are enjoying the new books, they are great! Although having the correct answers is good for speed the incorrect answer sparked a discussion about why the answer was wrong - which was lots of fun 😀

I have a question about the Green Book 10 - Statistics - I am not sure if this is the right place to ask it? Also, disclaimer - I am not a maths teacher... I was looking through the book before handing it to my child. On page 17, Q 10.2.4 #1 - The answers for A and B are 6 and 3 respectively. I can only assume the answers are wrong? The dark purple section of the pie chart is larger than the light green section, so the answer must a bigger number (it must be 9 as it is a quarter of the 36 households). And I am not sure what "F" is for question 1c? Have I missed something? Thank you!
