Two cards are drawn together from a pack of 52 cards. What is the probability that one is a spade and one is a heart? (A) 3/20 (B) 29/34 (C) 47/100 (D) 13/102

Answer: (D)

Explanation: Number of ways to draw 2 cards from a pack of 52 cards = 52C2 = 1326. Number of ways to draw a spade from 13 spades = 13C1 = 13. Number of ways to draw a heart from 13 hearts = 13C1 = 13. Number of ways to draw a spade and a heart = 13 * 13 = 169. Therefore, required probability = 169/1326 = 13/102.
