Explanation:

Step1: Identify relevant values

The number of students who do not use Facebook is 71, and the total number of students is 219.

Step2: Calculate the percentage

The percentage formula is $\frac{\text{Number of non - users}}{\text{Total number of students}}\times100\%$. So, $\frac{71}{219}\times 100\%$.
$71\div219\approx0.3242$, and $0.3242\times100\% = 32.42\%$.

Step3: Round the result

Rounding 32.42% to the nearest percent gives 32%.

Answer:

32%
