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.

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.

How does 4*3=12? I'm not getting it. Can any one explain it?

@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..!
