Question

Suppose that the joint probability of having malaria and having a fever is 1% and the joint probability of having the flu and having a fever is 2%. Additionally, suppose we take the world population to be 7 billion, the number of people worldwide currently infected with malaria 200 million, and the probability of having a fever if infected with the flu to be 40%.

Question 1 What is the probability that a person has fever given that they have malaria?

Question 2 How many people likely have the flu?

Question 3 From the given information alone, is it possible to compute the probability of having the flu given that one has a fever?
