Answer

A ∪ U = {1,2,3,4,5,6,7}

Work Step by Step

A ∪ U U = {1,2,3,4,5,6,7} A = {1,3,5,7} The set A ∪ U represents all the elements of set A and elements of set U that are not present in 'A' . The elements of U that are not in A are 2,4,6. The elements of A ∪ U are 1,2,3,4,5,6,7. Therefore set A ∪ U = {1,2,3,4,5,6,7}
