Answer:
The completed truth table is attached
Explanation:
To answer your specific question, the last column is a conjunction (AND) of the third column and fifth columns
Third column is A V B
Fifth Column is ~(A ∧ B) which is the negation of A ∧ B namely the value in the 4th column
I will explain for the first row
A ⇒ T, B ⇒ T
A ∨ B ⇒ T ∨ T ⇒ T
A ∧ B ⇒ T ∧ T ⇒ T
~(A ∧ B) ⇒ ~ T ⇒ F
(A V B) ∧ ~(A ∧ B) ⇒ T ∧ F ⇒ F
You can work out the other three rows using similar logic
