Question

Solve this:
6 (i) If U = x : 0 ≤ x ≤ 10 ,   x ∈ W and A
= x : x   i s   a   m u l t i p l e   o f
  3 , find A'
(ii) If U is the set of natural numbers and A' is the set of all
composite number, then what is A ?

Sethu Raman · Answer

6 1) U is (0,1,2,3,4,5,6,7,8,9,10),
A is (3,6,9), A' is (0,1,2,4,5,7,8,10)

2) U is (1,2,3, )
A' is (4,6,8,9,10,12,14, ) ( A' is all non - prime numbers )
A is (2,3,5,7,11,13, ) ( A is all prime numbers )
