Final answer:
The elements in the set A AND B are 1, 3, and 7. The elements in the set A OR B are 1, 3, 7, 9, and 11.
Step-by-step explanation:
The question is asking for the elements in the set A AND B and A OR B, given the universal set U and subsets A, B, and C.
Given that U = {1, 3, 5, 7, 9, 11}, A = {1, 3, 7, 11}, B = {1, 3, 7, 9}, and C = {3, 7, 11}, we can find:
- A AND B = {1, 3, 7}
- A OR B = {1, 3, 7, 9, 11}
So, the elements in the set A AND B are 1, 3, and 7, and the elements in the set A OR B are 1, 3, 7, 9, and 11.
