Unique case of OR conditional reasoning

[lathlee]

Hi Guys, this is my question

Hypothetically
this is the correct diagram for the random question,

If (Negation) A & (Negation) B C


Now Contrapositive:

If


Negation C A Occurs ( I know it supposed to be OR)


Let's say a question in this logical game asks about B. B Can or Cannot occur, right?



But this is the dilemma I see: If B occurs isn't that

A

&

B

Hi Lathlee,

If I'm understanding your question correctly, then yes, C would mean that either A or B or both could occur, but that at least A or B must occur. So:

A + B C

then:

C A or B (or A + B)

Hope this clears things up!

Yep it does clear up a lot. thx
