A classic card problem. Two cards are missing from a pack of cards, and one is drawn. The probability that this card is a king is?
My solution so far-
If no king is missing, the probability of drawing a king is $4/50$.
If one king is missing, the probability is $3/50$, and if two are missing, it becomes $2/50$.
Since all these cases are possible, we add them up, to get $9/50$. Am I missing anything here?

Another way to look at this is to think of drawing three cards in a row. The first two will be designated as "missing", and you want to find the probability that the third card is a king. The probability is the same as the probability of any card being a king, which is 1/13.
