The probability is 54.0%.
Solución
Let the probability that a randomly selected American believes that some psychics can help solve murder cases be \( p = 46\% \).
Then, the probability that a randomly selected American does **not** believe that is given by:
\[
100\% - p = 100\% - 46\% = 54\%
\]
Thus, the probability (in percent form) is \(54.0\%\).

To find the probability of randomly selecting someone who does not believe that some psychics can help solve murder cases, you can subtract the percentage of those who do believe from 100%. Since \( 46\% \) believe in the psychic's ability, the calculation is: \[ 100\% - 46\% = 54\% \] So, the probability of randomly selecting someone who does not believe is \( 54.0\% \). Probability = 54.0%
