Question

Let U = {1, 2, 3, 4, 5, 6, 7}, A = {1, 2, 3, 5} and C = {1, 4, 7}. List all the members of the following set. ​  ​

Quizplus · Accepted Answer

This question requires knowledge of the union of sets. The set in question has the same first half as set A and the same second half as set C. Therefore, its members are any elements that are in either A or C, giving us {1, 2, 3, 4, 5, 7}. The correct answer is option C.
