If A = {2, 3, 3, 5, 2} and B = {5, 2, 3}, which statement is correct?
Answer and explanation
Correct answer: A = B because they contain the same elements
A set records membership, not the order or frequency in which an element is written. Thus A = {2, 3, 5}, because the repeated 3 and 2 do not create new elements. Set B also contains exactly 2, 3, and 5. Since A and B have precisely the same elements, they are equal, so option C is correct.
