`(AuuB) nn (A uu B^c) = A`

If A and B and C are three non-empty sets, then which of the following is/are not true ? (A) n(A xx B) = n(B xx C) hArr n(A) = n(C) (B) A - (B nn C) = (A - B) nn (A - C) (C ) A uu (B nn C) = (A uu B) nn (A uu C) (D) (A nn B) - C = (A-C) nn (B - C)

A uu(B nn C) is equal to : a) (A uu B)nn(A uu C) b) (A nn B)uu(A nn C) C) A uu(B uu C) d) none of these

A = (A nn B) uu (AB) and A uu (BA) = (A uu B)

For any tow sets A and B(A-B)uu(B-A)=(A-B)uu Ab(B-A)uu Bc*(A uu B)-(A nn B)d(A uu B)nn(A nn B)

If A = {1, 2, 3}, B= { 4, 5, 6} and C= { 7, 8, 9}, verify that : A uu (B nn C)= (A uu B) nn (A uu C) .

Let A = {1, 2, 3, 4}, B = {4, 6, 7, 8} and C = {2, 4, 6, 8}. Verify the following identity : A uu(B nn C)=(A uu B)nn(A uu C) .

Let A={1,2,4,5}B={2,3,5,6}C={4,5,6,7}* Verify the following identities: A uu(B nn C)=(A uu B)nn(A uu C)

Fill in the blanks with elements of that set . U = {1, 3, 5,8, 9, 10, 11, 12, 13, 15} A = {1, 11, 13} B= {8, 5, 10, 11, 15} A' = {...................} B' = {................} AnnB = {..........} (A nn B)' = {..............} AuuB = {..........} (A uu B)' = {..............} A' nn B' = {..........} 'A' uu B' = {..............} Verify (A nn B)' = A' uu B' (A uu B)' = A' nn B'

(A uu B)' uu (A' nn B) = A. A' B. B' C. phi D. U ANSWER : A

The set ( A uu B uu C) nn (A nn B^c nn C^c)^c nn C^c equals :
