A card is to be chosen at random from a shuffled deck. Find the probability that the card drawn is

a)the queen of clubs, given that it is an honor card. (I think it is a typo)
b) a red four, given that the face number is even.
c) a seven, given that the face number is prime.

ok, I don't think I answered the questions correctly. I think the answers to all three would be 1/51.

  1. What is an honor card? If an honor card is a face card (J,Q,K), then there are 12 honor (face) cards in a deck.
    So a)=1/12
    For b) there are 20 numbered cards that are even. There are 2 red fours, So, b)=2/20
