A card is drawn from a well shuffled deck of 52 cards. What is the probability of getting a jack of spade or a queen of heart? (Considering replacement)
(A) 2 / 13
(B) 1 / 2
(C) 1 / 13
(D) 1 / 26
Answer: (D)
Explanation: Probability = favorable outcome / total outcome
Total outcome = 52
Probability of getting a jack of spade = 1 / 52. Since, there is only one jack of spade.
Similarly, probability of of getting a queen of heart = 1 / 52. Since, there is only one queen of heart.
Probability of getting a jack of spade or a queen of heart = 1 / 52 + 1 / 52 = 2 / 52 = 1 / 26.
