Negate Question for LR (Negate Sufficient)

NeverstoplrngNeverstoplrng Yearly Member
in Logical Reasoning 39 karma

Hi All..Quick Q. On the following sentence, using rule 3 (pick one part of the relationship, negate it, then make it the sufficient condition):

"It's not over until the fat lady sings."

O>FLS (on this part, do I think of the negating on the "O, over" because I removed the "Not" in the sentence before it?
/FLS>/O

I keep getting confused on this because of the definition of Negate, i.e. to deny, to declare not to be true. Thanks so much!

    When I negate "not over" in this sentence I think, "for it to be over, I need the fat lady to sing!"

    Which is your - O > FLS

    I hope this makes sense! If you need more clarification, please let me know!

    If you have a double negative they are going to cancel each other out.

    "It's not over until the fat lady sings."

    So, applying group 3, negate sufficient:

    "If it's not not over → the fat lady sings"

    They cancel out:
    "If it's not not over → the fat lady sings"...

    "If it's over → the fat lady sings."

    You'll just do all of this in your head, of course.

    Ahhh okay thank you so much! This has been tripping me up, because I have felt like I was breaking the "rule" and not negating. Perfectly explained!
