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 answer:

p₁ =  74 %
p₂ =  50 %

Step-by-step explanation:

$p_1=100\cdot {\displaystyle \frac{86+62}{200}}=74\mathrm{\%}$

$p_2=100\cdot {\displaystyle \frac{14+86}{200}}=50\mathrm{\%}$
