If a card is drawn from a well shuffled pack of cards, the probability of drawing a spade or a king is__________?
Correct answer: D. 4/13
- A. 19/52
- B. 17/52
- C. 5/13
- D. 4/13
Explanation
There are 13 spades and 4 kings, but the king of spades is counted twice, so favorable cards = 13 + 4 - 1 = 16. The probability is 16/52 = 4/13. Students may choose 17/52 by adding the spades and kings without removing the overlap.
