Find the probability $P\left(E^{C}\right)$ if $P(E)=0.39$. The probability $P\left(E^{C}\right)$ is (Simplify your answer.)

Step 1 ：Given that the probability of event E, denoted as \(P(E)\), is 0.39

Step 2 ：The probability of the complement of event E, denoted as \(E^{C}\), is given by \(P\left(E^{C}\right) = 1 - P(E)\)

Step 3 ：Substitute \(P(E) = 0.39\) into the formula to find \(P\left(E^{C}\right)\)

Step 4 ：Calculate \(P\left(E^{C}\right) = 1 - 0.39 = 0.61\)

Step 5 ：Final Answer: The probability \(P\left(E^{C}\right)\) is \(\boxed{0.61}\)
