The total number of families is the sum of all values in the table, $21 + 126+54 + 99=300$.
Step2: Calculate number of non - homeowners
The number of non - homeowners is $54 + 99 = 153$.
Step3: Calculate percentage of non - homeowners
The percentage of non - homeowners is $\frac{153}{300}\times100% = 51%$.
Step4: Calculate number of families with no car or one car
The number of families with no car or one car is $21+54 = 75$.
Step5: Calculate percentage of families with no car or one car
The percentage of families with no car or one car is $\frac{75}{300}\times100%=25%$.
