Answer 1

First draw this rectangle to represent all 1000 customers. This will be called set U (for universal set)

Answer 2

Inside set U will be sets A and B

set A = set of people who ordered turkey
set B = set of people who ordered ham

Answer 3

we know that " 225 customers ordered neither turkey nor ham"

so 225 goes outside set A and outside set B, but it's inside set U

Answer 4

that leaves 1000 - 225 = 775 which live in this region



ie they are in A, or B, or in both A & B
