Question

Find the complement of set A in universe U. U is the set of whole numbers less than 10. A is the set of factors of 9. {1, 2, 4, 5, 6, 7, 8} {1, 3, 9} {1, 9} {0, 2, 4, 5, 6, 7, 8}

Answer 1

Answer: {0, 2, 4, 5, 6, 7, 8}

Step-by-step explanation:

Since U is the set of whole numbers less than 10 , then

U = { 0, 1,2,3,4,5,6,7,8,9}

Also , since A is the set of factors of 9 , then

A = { 1, 3,9}

The complement of A are the numbers in U that is not in A , that is

$A^{1}$ = { 0, 2,4,5,6,7,8,}
