Explanation
The answer indicates that 88% of the sample population did not have green eyes. This is also represented by the number 88, which could be the actual count of individuals without green eyes in the sample. The stacked bar chart likely displayed different eye colors as categories, and the green portion of the chart would represent the percentage of people with green eyes. Therefore, the remaining portion of the chart, which is not green, would represent the percentage of people without green eyes.

### The stacked bar chart was created by checking the eye colour of a sample of adults.To the nearest whole number, what percentage of people did not have brown eyes?
