Answer: 1/2
Explanation
The face cards are Jack, Queen, King. Since there are 4 suits, there are 3*4 = 12 face cards in total. Half of which are black, so 6 face cards are black (spades and clubs). The other 6 face cards are red (hearts and diamonds).
So 6/12 = 1/2 is the probability of getting a black card given it is a face card.
The phrasing "given that the card is a face card" means we can ignore the other non-face cards. Simply consider the deck as 12 face cards only.
