In a class of 35 students of Geography, following marks were obtained out of 10 marks in unit test -1, 0, 2, 3, 4, 5, 6, 7, 2, 3, 4, 0, 2, 5, 8, 4, 5, 3, 6, 3, 2, 7, 6, 5, 4, 3, 7, 8, 9, 7, 9, 4, 5, 4, 3. Represent the data in the form of a group frequency distribution.

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 X={1,2,3,{4,5},6,{7,8,9,10} then {4,5} sub X

If A = {1, 3, 9, 10, 21), B= {4, 6, 8, 10} and C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, then the value of A cap (B cap C) is
