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.

Given:

P(D)=0.001

P(T|D complement)=0.05

P(T|D)=1.00

please can anybody help..i'll really appreciate it..
