A music playlist has 38 songs: 18 are qawwalis, 24 are pop songs and 8 are tagged as both. How many songs are in at least one of the two groups?

  1. 10
  2. 26
  3. 4
  4. 34
Answer

D) 34

At least one = 18 + 24 - 8 = 34; first group only = 10; second group only = 16; exactly one = 26; neither = 38 - 34 = 4. So the answer is 34. SLO M-09-A-14 · Application
