In a survey of 60 families: 28 read Jang, 25 read Dawn, 20 read Express; 10 read Jang and Dawn, 8 read Dawn and Express, 6 read Jang and Express, and 3 read all three. How many read none of them?

  1. 9
  2. 52
  3. 8
  4. 11
Answer

C) 8

At least one = 28 + 25 + 20 - 10 - 8 - 6 + 3 = 52, so none = 60 - 52 = 8. SLO M-09-A-14 · Application
