A special test is given to people complaining of sever headaches. If someone has a brain tumor, the test is positive with a probability of .8 (80%). If they have no tumor, the test is positive with a probability of .1 (10%). only 4% (.04) of those tested actually have brain tumors. What is the probability of someone who tested positive has a brain tumor.© BrainMass Inc. brainmass.com June 3, 2020, 11:23 pm ad1c9bdddf
