Q. Given:\newlineSet A=4,9,10,11 A=4,9,10,11 \newlineSet B=4,8,10,12 B=4,8,10,12 \newlineWhat is the union of sets A and B?\newline{9,11} \{9,11\} \newline{4,8,9,10,12} \{4,8,9,10,12\} \newline{4,10} \{4,10\} \newline{4,8,9,10,11,12} \{4,8,9,10,11,12\}
  1. Union of sets AA and BB: Union of sets AA and BB means all elements from both sets, but each element listed only once.
  2. List elements from set A: List all elements from set AA: 44, 99, 1010, 1111.
  3. List elements from set B: List all elements from set B: 44, 88, 1010, 1212.
  4. Combine elements without repeating: Combine the elements without repeating any: 4,9,10,11,8,124, 9, 10, 11, 8, 12.
  5. Put combined elements in order: Put the combined elements in order: 4,8,9,10,11,124, 8, 9, 10, 11, 12.
