a poll showed that 68% of americans say they believe that some psychics can help solve murder cases. what is the probability (in percent form) of randomly selecting someone who does not believe that some psychics can help solve murder cases.



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%.
