If A = {2, 4, 6, 8} and B = {6, 8, 10, 12}, what is A ∪ B?
Answer and explanation
Correct answer: {2, 4, 6, 8, 10, 12}
The union A ∪ B contains every distinct element that belongs to A or B, or to both. Combining A = {2, 4, 6, 8} with B = {6, 8, 10, 12} gives 2, 4, 6, 8, 10, and 12. The repeated elements 6 and 8 are written only once because a set does not list duplicate elements. Hence option A is correct.
