The proportion of people in a given community who have Covid-19 infection is  0.005. A test is available to diagnose the disease. If a person has Covid-19, the probability that the test will produce a positive signal is 0.009 . If a person does not have the Covid-19, the probability that the test will produce a positive signal is  0.01.

1. What is the probability that the test will generate positive signal?


2. Which model/rule will best be good for solving the above problem and why?


3. Comment on the types of events you see in the problem and name them.
