If set $A$ has $p$ elements and set $B$ has $q$ elements,then the number of elements in $A \times B$ is:

If $A, B,$ and $C$ are three sets,then $A \times (B \cap C)$ is equal to:

If $A=\{2,4\}, B=\{3,4,5\}$,then $(A \cap B) \times (A \cup B) =$

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

The Cartesian product $A \times A$ has $9$ elements,among which are found $(-1, 0)$ and $(0, 1)$. Find the set $A$ and the remaining elements of $A \times A$.

Let $n(A) = 3$ and $n(B) = 3$ (where $n(S)$ denotes the number of elements in set $S$). Then,the number of subsets of $(A \times B)$ having an odd number of elements is:
