I have made a video explaining Question 3 on Venn Diagrams for some of my students, maybe this will be helpful for some of you.
Isn't a bit strange to add up the six figures and subtract from 200 to show that the last 2 areas have frequency zero? We were told right at the start that everyone was either full-time, part-time or contract staff, so if we are following usual Edexcel practice of drawing Euler diagrams instead of proper Venn diagrams*, we shouldn't draw any zone which isn't in either F, H or C in the first place.
I've discussed the question here: https://app.sugarsync.com/iris/wf/D1...9005673_66703\ in S1 2013_06 MAD Phil ans
*which would require 16 zones, 10 of which would be labelled as empty
