If `A = { 5,6,7 }` and B = `{ 7, 8, 9 }`, then `A uu B` is equal to :

If A = {5, 7, 8} and B = {9, 11}, then

If A = { 2 , 5, 8 , 7 } , B = { 6 , 7, 8 , 9 } ,then A ∩ B = A) { 5 , 8 , 7 } B) { 2 , 5, 7 } C ) { 7, 8 }

If A = {1,2,3,4,5,6,7} and B = {7,8,9,10} , then A-B equals :

If A = {1, 4, 7, 8},B = {4, 6, 8, 9} andC = {3, 4, 5, 7} be three subsets of a universal set U = { 1, 2, 3, 4, 5 , 6 , 7 , 8 , 9 } . Then, A cup ( B cap C ' ) is equal to

Let X = {1,2,3,4,5,6,7,8,9,10} be the universal set and A ={2,4,6,} , B = {1,3,7}, then A^(@) nn B^(@) is equal to .

If A = {1,2,3……..9} , B = {2,4,6,7,8} and C = {3,4,5,8,9,10} then (A - B) uu C is .

If A={1,4, 7,8}, B={4,6,8,9} and C={3,4,5, 7} be three subsets of a universal set U ={1,2, 3, 4,5, 6, 7,8, 9} . Then, A uu (Bnn C') is equal to
