Answer
There are $7.69\%$ respondents having answered 'Rarely' or 'Never'.
Work Step by Step
It is necessary to calculate the total number of respondents having answered 'Rarely' or 'Never', which is the total number of 'Rarely' and 'Never' responses.
$$118+249=367.$$
Next, the percentage of respondents having answered 'Rarely' or 'Never' can be figured out by dividing the total number of respondents having answered so by the total number of responses and multiply by $100\%$. In detail,
$$\frac{367}{4770}\times100\%\approx7.69\%.$$
There are $7.69\%$ respondents having answered 'Rarely' or 'Never'.
