Suppose the university has designed a e-mail spam filter that attempts to identify by looking for commonly occurring phrases in spam. E-mail analysis has shown that 80% of email is spam. Suppose that 10% of the spam email contain the phrase “Large inheritance”, whereas this phrase is only used in 1% of non-spam emails. Suppose a new email is received with the phrase ”Large inheritance”, what is the probability that it is spam?
