Hi

1100 people

 	      ≥ 1	Both	  1

Microwave	860				

DVD Player	740						

          1600	-590	= 1010

a. how many own either a microwave oven or a DVD player: 1010

b. how many own neither a microwave oven nor a DVD player: 1100-1010 = 90

c. How many own a microwave oven and do not own a DVD player = 860-590= 270
