P(not a face card | 4) = "Probability of NOT drawing a face card given you've drawn a four"

Since you know 100% that you've drawn a four card, and a four card is NOT a face card, this means that

P(not a face card | 4) = 0

Since it's impossible to draw a face card given that you know this information.
