Expert Solution
Step 1

Given that the domain of quantification is the Boolean values TRUE and FALSE.

A logical statement is said to be Tautology, if it is True for all possibilities.

Given that p and q are two statements.

We know that the compound statement p∨q is true if at least one of p or q is true, it is false when both p and q are false.

We know that the compound statement p⊕q is true if exactly one of the p or q is true and otherwise false.

We know that the truth table of p⇒q can be written as:

p q p⇒q
T T T
T F F
F T T
F F T
