State whether the following statement is true or false. Justify your answer.
${2, 3, 4, 5}$ and ${3, 6}$ are disjoint sets.

(B) False.
Two sets are disjoint if their intersection is the empty set,i.e.,$A \cap B = \emptyset$.
Given sets are $A = \{2, 3, 4, 5\}$ and $B = \{3, 6\}$.
Since $3 \in A$ and $3 \in B$,the intersection is $A \cap B = \{3\}$.
Since $A \cap B \neq \emptyset$,the sets are not disjoint.
