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?

Result

p1 =  74 %
p2 =  50 %

Solution:

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



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
