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.

About Ratio and Proportion

Ratios compare quantities in the same units, while proportions state that two ratios are equal. Problems cover simplification, division in a given ratio, direct and inverse variation, scale, and missing terms, with attention to the difference between a ratio and a fraction representing part of a whole.
