A standard deck of cards has 52 cards of four different suits (diamonds, spades, hearts, clubs). Each suit consists of numbered cards 1 (Ace) to 10, followed by Jack, Queen and King (face cards). Express all your answers as a percent rounded to the nearest tenth of a percent, if necessary.

(b) If one card is drawn randomly from a deck, what is the probability that it is not a face card?
(c) If one card is drawn randomly from a deck, what is the probability that it is a 5 of hearts or 7 of hearts?
(d) A card is drawn and then put back into the deck and reshuffled. Then a next card is drawn. What is the probability that both cards are clubs?
