P={2, 1,3, 9, 1/2}; Q = {1,21/2,3, 7} and R = {5, 4, 21/2}. Find P∪Q∪R

  • A (21/2)
  • B (1, 9)
  • C (1, 2, 3, 4, 5, 6, 7)
  • D (5, 4, 21/2)
  • E (1/2, 1, 2, 21/2, 3, 4, 5, 7, 9)

The correct answer is E. (1/2, 1, 2, 21/2, 3, 4, 5, 7, 9)

P = {2,1,3,9,1/2}; Q = {1,21/2,3,7}

R = {5,4,212}

P∪Q∪R = {1/2,1,2,21/2,3,4,5,7,9}

= {1/2,1,2,21/2,3,4,5,7,9}
