The Venn diagram below shows the dinner orders for a local restaurant. How many people did NOT order steak for dinner?
Steak, chicken & fish were order. In the Venn circles, the total that did not order steak was 56. There is 43 in the right lower corner of the rectangle that the circles are in. Is this included in the total?

yups, the 43 is the number of people who did not order anything.
