Give examples of unit sets

Answer:

if A = {1, 3, 5, 7} and B = {1, 2, 4, 6} then A ∪ B = {1, 2, 3, 4, 5, 6, 7} or

1) S = {ϕ} with an element ϕ.

2) A = {x : x is neither a composite nor a prime number} = {1}; having one single element 1 in it.

3) B = {x : x2 = 9; x is a positive integer} = {3} with an element 3.

4) C = {x : x is an integer; 1 < x < 3} = {2}; it has only one element 2 in it.
