Incongruent testDiscrete Mathematics Level pending
Suppose that 40% of the population of the community of Pathogen (population 60 00) have a virus. A test accurately detects the virus in 95% of the cases when the person has the virus , but FALSELY detects the virus in 10% of the cases when the person does not have the virus. EACH person is tested TWO times. If the two tests do not agree, the results are said to be INCONGRUENT . How many of the results would you expect to be INCONGRUENT?
note: Each of the 60 00 persons is given the test two times.
