A search engine has excellent accuracy, such that the probability of getting a relevant result for each search is 0.8. Assume that this probability is constant and that the probability of getting the relevant search results is independent of the previous search. a. Out of seven searches, what is the maximum chance of getting two irrelevant results? b. What is the probability that it will take at least three searches until an irrelevant result is found?
