Quizplus · Accepted Answer

The percentage of those who tested negative and actually have the disease is calculated by dividing the number of people who have the disease and tested negative (12) by the total number of people who tested negative (8887), then multiplying by 100 to get the percentage: $(12 / 8887) \times 100 = 0.135\%$, which rounds to 0.1%.
