Question

Of 200 people surveyed, 80 percent own a cellular phone and 45 percent own a pager. If all 200 people surveyed own a cellular phone, or a pager, or both,

what percent of those surveyed either do not own a cellular phone or do not own a pager?
(A) 35%
(B) 45%
(C) 55%
(D) 65%
(E) 75%

Answer 1

80% own a cell phone, so 20 % do not own a cell phone.

45% own a pager, so 55% do not own a pager.

20% + 55% = 75% don't own either.

The answer is E. 75%
