TS EAMCET · Maths · Probability
A diagnostic test has the probability 0.95 of giving a positive result when applied to a person suffering from a certain disease and a probability 0.10 of giving a positive result when given to a non-sufferer. It is estimated that \(0.5 \%\) of the population are suffering from the disease. If this test is now administered to a person from this population about whom there is no information relating to the incidence of this disease and the test gives a positive result, then the probability that he is a sufferer, is
- A 0.9545
- B 0.2194
- C 0.0455
- D 0.9499
Answer & Solution
