Conditional Probability

Question

A card is drawn from a pack of 52 playing cards. Find the probability that the card will be a king, given that it is a face card. (The face cards are the jacks, queens, and kings. Enter your probability as a fraction.)

Answer 1

If the deck only has face cards, or we assume we've already passed the probability that we have picked a face card, there are 4 kings out of 12 face cards, so 33%
