A) the probability that the card will be diamond is 1/2
B) the probability of an ace of heart is 1/52
C) the probability of not a heart is ¼
D) the probability of king or queen is 1/26
Correct Answer: B
Solution :
Total number of cards = 52 Total number of diamond cards =13 [a] P (diamond cards) = 13 / 52 = 1 /4 [b] P (an ace of heart) =1/52 [c] P (not heart) \[=1-\frac{1}{4}=\frac{3}{4}\] [d] P (king or queen) \[=\frac{4}{52}+\frac{4}{52}=\frac{8}{52}=\frac{2}{13}\]
