Let $A = \{a, b, c\}, B = \{b, c, d\}, C = \{a, b, d, e\}$. Then $A \cap (B \cup C)$ is

If $A$ and $B$ are disjoint,then $n(A \cup B)$ is equal to

Consider the sets $A$ and $B$ where $A = \{2, 4, 6, 8\}$ and $B = \{6, 8, 10, 12\}$. Find $A \cap B$.

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

Draw the appropriate Venn diagram for the following expression: $A^{\prime} \cup B^{\prime}$

If $A = \{ x : x \text{ is a natural number} \}$,$B = \{ x : x \text{ is an even natural number} \}$,$C = \{ x : x \text{ is an odd natural number} \}$,and $D = \{ x : x \text{ is a prime number} \}$,find $A \cap B$.
