Once observe the question clearly, that jack, king, and queen are 3 cards than each one 4 so 4 + 4 + 4 = 12 I think it may help you.

Total there are 16 face cards jack, queen, king and ace.
But according to question it is mentioned only (jack, queen and king) so we have taken 12 instead of 16 I think you might have got what I mean to say.

Yes, I got it. As per the question, it is 12. But actually, it is 16.

Correct answer 3/13.
P(1/13+1/13+1/13) = 3/13.
P(1/13+1/13+1/13) = 3/13.

Ace is also a face card. But in question, they have clearly mentioned (king, queen, jack only).
So we consider only these to get the answer.
So it is clearly 3/13.

@Sushmitha.
If the only king is mentioned as face card then you have to solve as per king only.

In the question itself they mentioned that face card (king, queen and joker) so 4c1+4c1+4c1/52c2=3/13.
