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?

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
