Draw a Venn Diagram first.

Answer 4

Total = 1000 customers.
Insert the appropriate numbers in the three sections of the overlapping circle.
Left part: Number of customers who bought Turkey ONLY.
Right part: Number of customers who bought Ham ONLY.
The middle, intersecting part: Number of customers who bought BOTH Turkey & Ham.
So that all the numbers add to a total of 1000 customers.
