Question: Software filters rely heavily on blacklists lists of known phishing

Software filters rely heavily on "blacklists" (lists of known "phishing" URLs) to detect fraudulent e-mails. But such filters typically catch only 20 percent of phishing URLs. Jason receives 16 phishing e-mails.
(a) What is the expected number that would be caught by such a filter?
(b) What is the chance that such a filter would detect none of them?
