Answer: 8/145

Step-by-step explanation: Rewriting the table

Positive and Negative stand for the result of the test

Yes and No stand for having the disease

Positive | Negative | Total

Yes | 137 | 8 | 145

No | 16 | 139 | 155

Total | 153 | 147 | 300

probability of getting someone who tests negative, given that he or she had the disease.

P (Negative | Yes) = P (Negative ∩ Yes) = 8

P (Yes) 145
