Researchers

Researchers ask 200 families whether or not they were the homeowner and how many cars they had. Their response was homeowner: 14 no car or one car, two or more cars 86, not homeowner: 38 no car or one car, two or more cars 62. What percent of the families have two or more cars? What percentage of families are homeowners?

Correct result:

p1 =  74 %
p2 =  50 %

Solution:

p1=100 86+62200=74%p_{1}=100 \cdot \ \dfrac{ 86+62 }{ 200 }=74 \%
p2=100 14+86200=50%p_{2}=100 \cdot \ \dfrac{ 14+86 }{ 200 }=50 \%
