In a pack of 52 playing cards, there are 2 red queens and 2 black jacks. 
Red queens and black jacks are removed from the pack. Then,
Number of remaining cards = 52 − 4 = 48
∴ Total number of outcomes = 48 

There are 4 king cards in the remaining pack of cards.
So, the favourable number of outcomes are 4.
∴ P(drawing a king) = \[\frac{\text{ Favourable number of outcomes }}{\text{ Total number of outcomes }} = \frac{4}{48} = \frac{1}{12}\]

  Is there an error in this question or solution?
