Sets And Venn Diagrams Mock Tests

The set {x : x is a prime number less than 10} written in roster form is

If A = {1, 2, 3}, the number of subsets of A is

If A = {1, 2, 3} and B = {2, 3, 4}, then A - B is

If A = {1, 2, 3} and B = {2, 3, 4}, then A ∩ B is

If A = {1, 2, 3, 4, 5} and B = {3, 4, 5, 6, 7}, then the number of elements in (A U B) minus (A intersection B) is

If A = {1, 2, 3} and B = {2, 3, 4}, then A ∩ B is

If A = {1, 2} and B = {3, 4}, then n(A × B) is
