Three cards are dealt from a standard 52-card deck. 1 A. What is the probability that all three cards are spades? Solution The probability of drawing one spade is 13/52 or 1/4. The odds of drawing another spade is 12/51. The odds of drawing a third spade is 11/50. If you multiply (1/4 * 12/51 * 11/50), you get 132/10200. This simplifies to 11/850..
