Hi, I was making up statements to practice and I'm confused about how "no" works when there is a double negative (or what I think is double negative). The statement reads: "No one who fails to come to the party is David."
Based on JY's lesson, we isolate "no" as a Group 4 Necessary Condition indicator. The first idea is "Fail to Come to the Party" (FTCTP) and the second idea is "David" (D). So, I pick either of the two ideas, negate it, and make it a necessary condition. I chose the first idea.
D --> /FTCTP
which, I think, can be rewritten as D --> CTP since "Not Fail to Come to the Party" is essentially "Come To the Party"
Is this lawgic accurate? Some of my friends are suggesting that because of the "fail to", the correct lawgic would be: CTP --> D
and now im confused :(
thanks in advance for your input!
