Lesson: Venn Diagrams

Comment on Venn Diagrams

Hi Brent
thank you so much for lessons

Could you please explain me how did you get 21 homes (2 min 15 sec)
Because I'm confused. I used formula for such diagrams:
Total= A+B+C - (Sum of 2 overlaps) + all three+neither
=15
What is the specification for such diagrams in the integrated reasoning session?
what I got wrong?

The equation is actually:
Total = Group1 + Group 2 + Group 3 - (sum of 2-group overlaps) - 2(all three) + Neither
= 9 + 10 + 9 - 3 - 2(5) +6
= 21

Cheers,
Brent
