Since the question is an OR case, we add the probabilities...
The probability of picking a king is 4/52 or 1/13 and
the probability of picking a red card is 26/52 or 1/2, we add
1/13 + 1/2 =
2/26 + 13/26 =
15/26
Thus 15/26 is the probability of any one card be a king or red.
To do it twice (after first replacing the card), one would then multiply
15/26 by itself, giving us 225/676.
To do it in either card, we add 15/26 + 15/26 = 15/13...or a certainty...
It is not clear how we draw the two cards.
