Question

Help me with this please and thank you!! :)

Answer 1

Explanation:

• 
  `A \cap C` denotes the set of elements in both A and C, which is
  `\{20, 24, 28\}`.
• 
  `B^(C)` denotes the complement of set B, which is the set of all elements that are in the universal set that are not in set B. In this case, this set is
  `\{3, 4, 5, 6, 8, 11, 13, 16, 17, 19, 20, 22, 23, 24, 25, 26, 27, 28\}`
