Q1: What is the correct definition for the union of two sets $A$ and $B$?
A1: $A \cup B = { x \mid x \in A \vee x \in B }$
A2: $A \cup B = { x \mid x \in A \wedge x \in B }$
A3: $A \cup B = { x \mid x \in A \wedge x \in \neg B }$
A4: $A \cup B = { x \mid x \in A \text{ and }x \in B }$
Q2: What is the correct definition for the intersection of two sets $A$ and $B$?
A1: $A \cap B = { x \mid x \in A \vee x \in B }$
A2: $A \cap B = { x \mid x \in A \wedge x \in B }$
A3: $A \cap B = { x \mid x \in A \wedge x \in \neg B }$
