The probability of having a positive test on a non-sick person is 24.32%.

Step-by-step explanation:

The probability of having a POS and not having tuberculosis, can be defined as the probability of getting a false positive.

The amount of positive test will be

1) The positive test of sick persons

P(test=pos;person=sick)=0.744*0.05=0.0372

2) The positive test of not-sick persons (false positives)

P(test=pos;person=sick)=(1-0.744)*0.95=0.256*0.95=0.2432

The amount of positive test will be

1) The negative test of non-sick persons

P(test=neg;person=non-sick)=0.7653*0.95=0.727

2) The negative test of sick persons (false negatives)

P(test=neg;person=non-sick)=(1-0.7653)*0.05=0.2347*0.05=0.0117
