Question: Probability, Bayes’ Theorem: A Covid-19 test produces false negatives 2% of the time and false positive 5% of the time. 10% of a city has the virus. Answer the following questions: If a person test negative, what is the probability that the person carries the virus? What is the probability that a person carrying the virus tests negative three times in a row through independent tests? What is the probability that someone who tests negative twice in a row of independent tests is a healthy person? Considering that the test has low false negative and false positive rates, please reflect on the results you obtained in parts (i) and (ii).
