Hey everyone..this is my firts post..I can't solve this problem..can somebody help me pls..
1.) Assume that a test to detect a disease whose prevalence is (1/1000) has a false positive rate of 5% and a true positive rate of 100%. What is the probability that a person found to have a positive result actually has the disease, assuming that you know nothing about the person's symptoms?
Define events: D= the event that the person has the disease
T= the event that the test result is positive.
