उत्तर

In a pack of 52 playing cards, there are 2 red jacks, 2 red queens and 2 red kings. 
All the red face cards are removed from the pack. Then,
Number of remaining cards = 52 − 6 = 46
∴ Total number of outcomes = 46 

There are 6 face cards (2 black jacks, 2 black queens and 2 black kings) in the remaining pack of cards.
So, the favourable number of outcomes are 6.
∴ P(drawing a face card) =  Favourable number of outcomes  Total number of outcomes =646=323
