What are the chances that a person who is murdered actually knew
the murderer? The answer to this question explains why a lot of

probabilities. (Round your answers to four decimal places.)
(a) at least 35 of the victims knew their murderers
(b) at most 48 of the victims knew their murderers
(c) fewer than 30 victims did not know their murderers
