what I did is P(a Club or a king)= (13+4)/52=0.327 But the answer is wrong. Can someone explain me where I did wrong and what would be the correct way to solve?

You counted the king of clubs twice, once as a king and once as a club. There are only $13+4-1$ cards that are either a king or club, where $1$ is the number of cards that are both. You may have seen $P(A \cup B)=P(A)+P(B)-P(A \cap B)$ and you have lost the third term.
