3. There’s a zombie virus outbreak. The virus has
already infected 2% of the world's population. The infected people
will eventually turn into zombies, so we want to isolate them now,
before they become truly dangerous and infect other people.
The scientists in AC Labs invented a test kit for the virus. The
test’s sensitivity is 95% (i.e., for 95% of the infected people the
test result will be positive) and specificity is 95% (i.e., 95% of
the non-infected the test result will be negative).
A person is tested, and the test kit shows a positive result. What
is the likelihood that the tested person really is infected?
Explain your answer.

RBV testing Suppose that 1% of all people are infected with the rare banana virus (RBV). There is a test to detect the RBV: if you do have the RBV, then the test will correctly detect this 99% of the time; if you do not have RBV, then the test will correctly indicate this 97% of the time. We assume that if the RBV test is given repeatedly to the same person, then the test results are independent of cach...

A certain virus infects one in every 300 people. A test used to detect the virus in a person is positive 80% of the time if the person has the virus and 5% of the time if the person does not have the virus. (This 5% result is called a false positive.) Let A be the event "the person is infected" and B be the event "the person tests positive". a) Find the probability that a person has the virus...

2. A rare disease affects 1% of the population. A test has a sensitivity of 98%, i.e., it will give a positive result 98% of the time that a person actually has the disease. The same test also has a specificity of 95%, i.e., it will give a negative result 95% of the time when a person does not have the disease. Denote the event that a randomly person has a disease by D, and the event that a randomly...
