Hi,

Note: U indicates all the distinct elements in both sets.  

      ∩ indicates only those elements they have in common.

Given A = {1,2,3,4,5,6}, B = {1,2}, and C = {6, 7}. 

a) A ∩ B = {1,2}

b) A U C = {1,2,3,4,5,6,7} 

c) B U C = {1,2,6,7}

d) (A U B) ∩ C = {6}

e) A U (B U C) = {1,2,3,4,5,6,7}

f) (A ∩ B) ∩ C = {}  NULL Set

g) (A ∩ B) U C = {1,2,6,7}
