In a class of 26 students, 11 play cricket, 13 play hockey and 4 play both. How many students are in at least one of the two groups?

  1. 7
  2. 20
  3. 6
  4. 16
Answer

B) 20

At least one = 11 + 13 - 4 = 20; first group only = 7; second group only = 9; exactly one = 16; neither = 26 - 20 = 6. So the answer is 20. SLO M-09-A-14 · Application
