the words in emails marked as spam by the user. If emails marked as spam then
the word "offer" appears in 15% of the mails. Assuming 0.5% of mail includes
the word "offer” if they are non-spam. 50% of all emails received by the user are
spam that means rest 50% of emails are non-spam. Find the probability that a
mail is
spam given that the word "offer"
appears
in it.
