Question

)A medical test correctly indicates that 97% of the affected population has a disease but incorrectly indicates that two percent of the healthy population has the disease. If 5% of the population has the disease what is the probability that a person who is diagnosed with the disease actually does?

Answer 1

Explanation:

The probability that a person who is diagnosed with the disease actually has it is 97%.

This is because 97% of the affected population has the disease, and only 2% of the healthy population shows a positive result.

Therefore, if a person is diagnosed with the disease, there is a 97% chance that they actually have it, and only a 3% chance that the test was false-positive.
