What percentage of the people surveyed cannot swim?

A. [tex]$12 \%$[/tex]
B. [tex]$18 \%$[/tex]
C. [tex]$40 \%$[/tex]
D. [tex]$6 \%$[/tex]

Answer :

To find the percentage of people surveyed who cannot swim, we look at the relative frequency table provided and focus on the relative frequencies for adults and children who cannot swim.

1. Identify the relative frequencies:
- For adults who cannot swim: 0.06
- For children who cannot swim: 0.12

2. Add the relative frequencies:
- Total relative frequency of people who cannot swim = 0.06 (adults) + 0.12 (children) = 0.18

3. Convert the total relative frequency to a percentage:
- To convert a relative frequency to a percentage, multiply by 100.
- Total percentage of people who cannot swim = 0.18 * 100 = 18%

Therefore, the percentage of people surveyed who cannot swim is 18%. The correct answer is B. 18%.
