    Names and True and False??? I need help

    I really get lost with these kind of problems. They just confuse me so much. I need some help. Thanks for you help in advance




    4 STUDENTS ONE OF WHOM HAD COPIED HOMEWORK MADE THE FOLLOWING STATEMENTS WHEN QUESTIONED BY THE ASSISTANT PRINCIPAL

    ANABELLE: ZAY DID IT

    ZAY: DEIRDE DID IT

    GUSTAVO: I DIDNT DO IT

    DEIRDE: ZAY LIED WHEN HE SAID I DID IT!

    IF ONLY ONE OF THESE FOUR STATEMENTS IS TRUE WHO WAS THE QUILTY STUDENT? WHCIH STATEMENTS ARE TURE AND WHICH AE FALSE IN THIS CASE?

    IF ONLY OE OF THSES FOUR STATEMENTS IS FALSE WHO WAS THE QUILTY STUDENT? WHICH STATEMENTS ARE TRUE AND WHICH ARE FALSE IN THIS CASE?

    why are you shouting?

    there may be an easier way to do this. but we can simply do this by cases.

    Assume Anabelle is telling the truth. then Zay's statement is false, Gustavo's is true, and Deidre's is true. So in this case, only one statement is false, so this answers the second question.

    now assume Zay is telling the truth, what does that mean? what about if Gustavo is true? or Deidre?
