Which option is a correct example of equal sets?
Answer and explanation
Correct answer: {1, 2, 3} and {1, 2, 2, 3, 3}
Two sets are equal when they contain exactly the same elements; order and repeated listing do not matter. In option A, the repeated 2 and 3 are counted only once, so {1, 2, 2, 3, 3} is simply {1, 2, 3}. The other pairs have different elements or different numbers of elements, so they are not equal.
