Proof of the Equality of Statements A v B and A * B

To prove the equality of the statements A v B and A * B, we can use the logical equivalence between the two statements.

The logical equivalence is based on the truth tables for the logical operators. In this case, we can use the truth tables for the "or" (v) and "and" (*) operators to demonstrate the equality of the two statements.

Truth Table for A v B (A or B)

| A | B | A v B | |---|---|-------| | T | T | T | | T | F | T | | F | T | T | | F | F | F |

Truth Table for A * B (A and B)

| A | B | A * B | |---|---|-------| | T | T | T | | T | F | F | | F | T | F
