From a survey of 100 college students, a marketing research company found that 35 students owned iPods, 25 owned cars, and 5 owned both cars and iPods
How many students owned either a car or an iPod (but not both)?
How many students do not own either a car or an iPod?

Draw a Venn diagram
overlap between cars and Ipods is 5
so Ipod alone = 35-5 = 30
and car alone = 25-5 = 20
so Ipod or car but not both = 30+20 = 50
Ipod and car = 35
car alone = 20
sum = 55
100 - 55 = 45 own nothing
