Answer:

There are 12 face cards (J, Q & K for each of the 4 suits - diamonds, hearts, clubs and spades) and 13 cards of spade. Let A be the event of drawing a face card and B be the event of drawing a spade. The required probability is P (A U B) = P (A) + P (B) - P (AB). Now, P (A) = 12/52, P (B) = 13/52 and P (AB) = 3/52 Hence, P (A U B) = 12/52 + 13/52 - 3/52 = 22/52 = 11/26.
