In a standard 52 card deck, there are 13 clubs and 12 face cards, three of which are clubs, so there are 22 (13 + 12 - 3) different ways of drawing a club or a face card. Thisâ¦ is a probability of 22 in 52, or 11 in 26, or about 0.4231.
  The probability of pick â¦ ing a card in any suit is 52 in 52, or 1.   Since there are now only 12 cards in the first suit, the probability of picking a card in the same suit is 12 in 51, or 4 in 17, or 0.2353.here are 13 spades in a standard deck of cards. â¦ There are four aces in a standard deck of cards. One of the aces is a spade. So, 13 + 4 - 1 = 16 spades or aces to choose from. Since we have a total of 52 cards, the probability of selecting an ace or a spade is 16 / 52 or approximately 30.8%.
