B= The boy went home
C= The grass is red
(B->C)^(C->B) or its B <-> C
I might be too drunk and stupid ATM but I only see conditional logic here. The confusing part to me is that there's no "if" in front of the first statement. But it's still a proposition because it's describing a state that is dependent on a condition.
So I'm still leaning towards neither. There is nothing in that sentence that states that the boy went home or that the grass is red. It only describes conditions if either of them matches those properties. My English as a second language might be interfering here.
... along with the 14 glasses or so of whiskey I drank. :-D
I’ve quit drinking for a year now. Ran into the law and ever since I’ve put down the sake
I need to do the same. I've been trying to wean it by adding loads of water and less and less whiskey gradually.
I sobered up now after waking up and I might have made a very silly assumption thinking this was a multiple-choice question (also I'm so ridiculous that I misread the variables as A and B rather than B and C) rather than a question asking for symbolic notation!
I think (B->C) & (C->B) can be simplified down to B<->C so perhaps going along with your answer but simplified:
(B->C) & (C->B) = B<->C
The boy went home iff (if and only) if the grass is red: B<->C.
(If B then C) And (If C then B): (B->C) & (C->B) =
B iff C: B<->C
So was I right?
I believe so with the second answer using <-> (material equivalence/biconditional/iff). I would double-check that though since it's been around 20 years since I had to do such exercises.

Nope.
you just translate the symmetric logic to symbolic logic.
do you think my answer was right? i think it was
wdym?
excuse you?
no wait. is my answer right?
