Please help me in solving the question number-2(i) A-B

2. Let A = {2, 4, 6, 8, 10}, B = {4, 8, 12, 16} and C = {6, 12, 18, 24}. Using Venn diagrams, verify that:
(i) (A ⋃ B)⋃ C = A ⋃ (B ⋃ C)
(ii) (A ∩ B) ∩ C = A ∩ (B ∩ C)

Dear student,
i) By Venn diagram, we have

From the last above images we get, (A U B) U C = A U (B U C) 
ii) 
By Venn diagram, we have

Clearly from (2) and (4) we get,
 (A n B) n C = A n (B n C)
Regards
