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
