Answer:
(A U B U C)={ 3,6,8,9,12,13,14,15,16,18,21,23,24,25,26,30}
(A n B n C) = {14,15}
Step-by-step explanation:
![S= \{ 1,2,3...,28,29,30 \}\\\\A = \{13,14,15,16 \}\\B= \{3,8,9,12,14, 15,21,30 \}\\C = \{3,6,14,15,18,23,24,25,26 \}](https://tex.z-dn.net/?f=S%3D%20%5C%7B%201%2C2%2C3...%2C28%2C29%2C30%20%5C%7D%5C%5C%5C%5CA%20%3D%20%20%5C%7B13%2C14%2C15%2C16%20%5C%7D%5C%5CB%3D%20%5C%7B3%2C8%2C9%2C12%2C14%2C%2015%2C21%2C30%20%5C%7D%5C%5CC%20%3D%20%5C%7B3%2C6%2C14%2C15%2C18%2C23%2C24%2C25%2C26%20%5C%7D)
Union of sets is the combination of all the values in the given set into one set
![A \:U \:B \:U \:C = ?\\\\(A \:U \:B \:U \:C ) =\\ \{3,6,8,9,12,13,14,15,16,18,21,23,24,25,26,30\}](https://tex.z-dn.net/?f=A%20%5C%3AU%20%5C%3AB%20%5C%3AU%20%5C%3AC%20%3D%20%3F%5C%5C%5C%5C%28A%20%5C%3AU%20%5C%3AB%20%5C%3AU%20%5C%3AC%20%29%20%3D%5C%5C%20%5C%7B3%2C6%2C8%2C9%2C12%2C13%2C14%2C15%2C16%2C18%2C21%2C23%2C24%2C25%2C26%2C30%5C%7D)
Intersection of sets is the combination of all the common terms in each set into one set.
![(A \:n \:B \:n \:C ) = ?\\\\(A \:n \:B \:n \:C ) = \{14,15\}](https://tex.z-dn.net/?f=%28A%20%5C%3An%20%5C%3AB%20%5C%3An%20%5C%3AC%20%29%20%3D%20%3F%5C%5C%5C%5C%28A%20%5C%3An%20%5C%3AB%20%5C%3An%20%5C%3AC%20%29%20%3D%20%5C%7B14%2C15%5C%7D)
