Question

Find A cup(B cap C) . A = \{1, 4, 6, 7\}; B = \{3, 4, 5\}; C = \{2, 4, 8\}; \{1, 4, 6, 7\} 4 } \{1, 2, 3, 4, 5, 6, 7, 8\}

Answer 1

{1, 4, 6, 7}

Explanation:

Answer 2

The only common element between B and C is 4, so B ∩ C = {4}.

4 is also already contained in A, so B ∩ C is a subset of A, and thus

A U (B ∩ C) = A = {1, 4, 6, 7}
