Answer :
The probability of randomly selecting someone who does not believe that some psychics can help solve murder cases is 32%.
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Since, the probability of randomly selecting someone who believes that some psychics can help solve the murder cases is P = 0.68.
[tex]\implies Q = 1-0.68 = 0.32[/tex]
Therefore, the probability of randomly selecting someone who does not believe that some psychics can help solve the murder cases is 32%.
