Answer:
What is the meaning of the difference of P and Q *? ... Step-by-step explanation: “P or Q” MEANS EXACTLY THE SAME AS “Q or P”; the two compound sentences are true in exactly the same situations. If P is false, both parts of this “or” sentence are false, and thus the compound “or” sentence is false.
