Q3- A bacteria infects 2% of people. It is possible to detect the bacteria in a person using a test. The test is positive (tells that there is infection) 1% of the time even though the person is not infected; this situation is called false positive. The test is negative (indicates no infection) 10% of the time even though the person is infected; this is called false negative. Using Bayes' theorem calculate the probability that a person who tests positive actually has the disease.
