Are : (Could be true/ Could be false/Not necessarily false/not necessarily true) logically equivalent?
Please help me understand my flaw in reason or if it is a pointless distinction. I have added my idea onto the end based on last slide if we're converting to true:
Which one of the following statements can be false?
C: Not nec true + (could be true)
IC: Must be True
Which one of the following must be false?
C: cannot be true
IC: could be true + (Not nec true )
Each of the following could be false EXCEPT:
C: Must be true
IC: Not nec true + (could be true)
All of the following statements must be false EXCEPT:
C: could be true + (Not nec true)
IC: cannot be true

Hi, I'm not sure I'm understanding your questions here. Are you asking which statements put together make another statement?

Hey Emil. Sorry this question got improperly tagged. I was still new to this website and drooling on my keyboard. It's from the logical reason video section with the yin-yang slides at the end.
Take for example: Student A could have red hair and Student A does not necessarily have red hair.
Are these logically the same meaning?
I just wanted to check going forward that it would be impossible to see two question choices like this together and have one of them still be right.

Ah I see now, my apologies! I think your understanding of what would be correct and what would be incorrect is spot on from your original question. These can be a bit tricky when they are abstract, when when seeing them in real questions, it usually feels a bit more intuitive.
