Total number of people who own either phone or pager = Total number of people who own phone + Total number of people who own pager - Total number of people who own both phone and pager

Taking percent values...

100% = 80% + 45% - Both
Both = 25%

Percent of those surveyed either do not own a cellular phone = 80% - 25% = 55%

Percent of those surveyed either do not own a pager = 45% - 25% = 20%

Percent of those surveyed either do not own cellular phone or do not own a pager = 55% + 20% = 75%

The correct answer: E

Hope this helps!

we can try as follows:

\(80%\) who own cellular phone \(= 160\).
\(45%\) own pager \(= 90\)

Total who own cellular phone \(= 160+90=250\). However, the total number of people is \(200\) so \(250-200=50\) people own both.

Now we need people who either own a cp or a pager (but not both), so we subtract the \(50\) from \(200=150\) is our required population.

\(\left(\frac{150}{200}\right)*100 = 75\).

Option __E__

We can use the formula for overlapping sets for this problem:

Total = #Cell + #Pager - Both + Neither

200 = 160 + 90 - x + 0

200 = 250 - x

50 = x

We see that 50 individuals own both a cell phone and a pager. Thus, the number of people who own a cell phone and not a pager is 160 - 50 = 110.

Similarly, of the 90 individuals who own a pager, there are 90 - 50 = 40 who own a pager and not a cell phone.

Thus, there are 110 + 40 = 150 who either do not own a cell phone or do not own a pager.
This number represents 150/200 = 3/4 x 100% = 75% of the people surveyed.
