State whether the following statement is true or false. If the statement is false, rewrite the given statement correctly. If A = {1, 2}, B = {3, 4}, then A xx (B nn phi) = phi .

State whether each of the following statetments is true or false. If the statement is false, rewrite the given statement correctly. If A ={1,2}, B = {3,4} then A xx ( B cap phi) = phi

If A = {1,2,3}, B= {3,4,5}, then (A nn B) xx A is

If A = {1, 2} and B = {3, 4} then write A xx B .

If A = {1, 2, 3}, B = {3, 4, 5}, then (A nn B) xx A is

If A = {1, 2, 3}, B = {3, 4, 5}, then (A nn B) xx A is

A= {1,2,3,4} , B={3,4,5} then (A xx B)nn (B xx A)=

State whether each of the following statements are true or false. If the statement is false, rewrite the given statement correctly. (i) If P= {m, n} and Q = {n, m}, then P xx Q= {(m, n),(n, m)}. (ii) If A and B are non-empty sets, then A xx B is a non-empty set of ordered pairs (x, y) such that x in A and y in B. (iii) If A={1,2}, B={3,4} then A xx (B cap phi)=phi
