Answer

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

Steps

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 $\boxed{0.61}$
