Question 878950: A single card is drawn from a standard deck of cards. Find the probability if the given information is known about the chosen card. A face card is a jack, queen, or king.
P(face card|queen)

P(face card|queen) means "the probability that you draw a face card given you have drawn a queen"
That part "given you have drawn a queen" means it is 100% known that you pulled out a queen. This is "given" to you. It's assumed to be true.
Since all queens are face cards, this means drawing a queen tells us we also drew a face card.
So if we're guaranteed a queen, then we are guaranteed a face card.
Making P(face card|queen) = 1
A probability of 1 represents 100% which is absolution certainty.
