King, Queen and Jack are called as FACE cards.
King, Queen, Jack and Ace are called as HONOR cards.
King, Queen, Jack and Ace are called as HONOR cards.

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

n(s) = 52c1.
n(e) = 4c1+4c1+4c1.
p(e) = 12/52 = 3/13.
n(e) = 4c1+4c1+4c1.
p(e) = 12/52 = 3/13.

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

Ace also a face card.

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.

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