@Rajarshi,
"AND" means "MULTIPLICATION","OR" means "ADDITION"
In this we are given to draw a single card from J, Q, K means
J OR Q OR K means 4+4+4.
Hope you are cleared.
Thanks..!

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.

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.

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