If $A, B, C$ are three sets, then $A \cap (B \cup C)$ is equal to
$(A \cup B) \cap (A - C)$
$(A \cap B) \cup (A \cap C)$
$(A \cup B) \cup (A \cup C)$
None of these
If $A \cap B = B$, then
If $A = \{1, 2, 3, 4, 5\}, B = \{2, 4, 6\}, C = \{3, 4, 6\},$ then $(A \cup B) \cap C$ is
If $A$ and $B$ are disjoint, then $n(A \cup B)$ is equal to
State whether each of the following statement is true or false. Justify you answer.
$\{2,6,10,14\}$ and $\{3,7,11,15\}$ are disjoint sets.
If $A = \{ x:x$ is a natural number $\} ,B = \{ x:x$ is an even natural number $\} $ $C = \{ x:x$ is an odd natural number $\} $ and $D = \{ x:x$ is a prime number $\} ,$ find
$A \cap B$
