Question

A poll showed that 52.5% of Americans say they believe that some psychics can help solve murder cases. Whatis the probability of randomly selecting someone who does not believe that some psychics can help solvemurder cases.Probability =% (Please round your answer to one decimal place.)

Answer 1

We need to find the probability of randomly selecting someone who does not believe that some psychics can help solve murder cases.

We know that the probability of randomly selecting someone who believes it is:

`52.5\%`

Since the set of those who do not believe it is complementary to those who believe it, the probability to randomly selecting somen who does not believe is given by:

`100\%-52.5\%=47.5\%`

Therefore, the probability of randomly selecting someone who does not believe that some psychics can help solve murder cases is 47.5%.
