If $A = \{ 2, 4, 5 \}$ and $B = \{ 7, 8, 9 \}$,then $n(A \times B)$ is equal to

If $A = \{2, 3, 5\}$ and $B = \{2, 5, 6\}$,then $(A - B) \times (A \cap B)$ is:

If $A = \{a, b\}$,$B = \{c, d\}$,$C = \{d, e\}$,then $\{(a, c), (a, d), (a, e), (b, c), (b, d), (b, e)\}$ is equal to

Let $A, B, C$ be three sets such that $n(A \cap B) = n(B \cap C) = n(C \cap A) = n(A \cap B \cap C) = 2$. Then $n((A \times B) \cap (B \times C))$ is equal to -

If $A = \{1, 2, 4\}, B = \{2, 4, 5\}, C = \{2, 5\},$ then $(A - B) \times (B - C)$ is

Let $A = \{1, 2\}$ and $B = \{3, 4\}$. Find $A \times B$. How many subsets will $A \times B$ have? List them.
