$\left\{1 , 3 , 5\right\} .$

#### Explanation:

We have, the Sample Space $U = \left\{1 , 2 , 3 , 4 , 5 , 6\right\} .$

Given the Event $A = \left\{2 , 4 , 6\right\} .$

Recall that the Complement Event of $A ,$ denoted by $A '$ is

the set of all outcomes not favorable to the occurrence of

$A .$

Clearly, $A ' = \left\{1 , 3 , 5\right\} .$
