Suppose U = \{3, 5, 6, 8, 10, 11, 13, 17, 18\} is the universal set and A = \{3, 6, 11, 13, 17\} What is A'? Choose the correct answer. OA. \{5, 8, 10, 18\} O C. \{5, 8, 10, 11, 18\} OB. \{3, 8, 11, 17\} OD. \{5, 6, 8, 10, 18\}

Answer 1

A' refers to the complement of set A, which includes all the elements in the universal set U that are not in set A. Looking at the universal set, we can see that the elements in A' are: 5, 8, 10, and 18. Therefore, the correct answer is OA. {5, 8, 10, 18}.
