Question

Let S be the universal set, where:
S={1,2,3,...,28,29,30}
Let sets A and B be subsets of S , where:

Answer 1

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:

$S= \{ 1,2,3...,28,29,30 \}\\\\A = \{13,14,15,16 \}\\B= \{3,8,9,12,14, 15,21,30 \}\\C = \{3,6,14,15,18,23,24,25,26 \}$

Union of sets is the combination of all the values in the given set into one set

$A \:U \:B \:U \:C = ?\\\\(A \:U \:B \:U \:C ) =\\ \{3,6,8,9,12,13,14,15,16,18,21,23,24,25,26,30\}$

Intersection of sets is the combination of all the common terms in each set into one set.

$(A \:n \:B \:n \:C ) = ?\\\\(A \:n \:B \:n \:C ) = \{14,15\}$
