Answer 2

For the given sets, we can perform various set operations.

1. A = {7, 2, 9, 4} B = {9, 2, 5}

Union of sets A and B (A ∪ B): A ∪ B = {7, 2, 9, 4, 5}

Intersection of sets A and B (A ∩ B): A ∩ B = {2, 9}

Set difference of A and B (A - B): A - B = {7, 4}

2. A = {8, 5, 6, 2} B = {9, 6, 5, 7}

Union of sets A and B (A ∪ B): A ∪ B = {8, 5, 6, 2, 9, 7}

Intersection of sets A and B (A ∩ B): A ∩ B = {5, 6}

Set difference of A and B (A - B): A - B = {8, 2}
