Question 1061753: Compute the probability that a person who tests positive actually has the disease.
A certain disease has an incidence rate of 0.3%. If the false negative rate is 4% and the false positive rate is 1%, compute the probability that a person who tests positive actually has the disease.
Answer by Edwin McCravy(20060) About Me  (Show Source):
You can put this solution on YOUR website!
The false positive rate is 1%, so the probability that somebody who tests
positive doesn't have the disease is 1% or 0.01.  Therefore the probability
that somebody who tests positive has the disease is 99% or 0.99.

Answer: 99%
