Question

Which statement is logically equivalent to "If Yoda cannot use a lightsaber then he cannot help Luke win the battle" ​

Answer 1

SOLUTION

A statement is logically equivalent to its contrapositive To form the contrapositive switch the "If" and "then" sections of the statement AND insert "NOTs" into each section Notice in this situation that inserting "NOTs" turns the thoughts positive (you are negating negative thoughts)
