I'm reading up on propositional logic, and I'm completely stuck on this example - spent the past few hours trying to figure it out! Any pointers would be appreciated.
There's 2 trees, each with signs on.
Sign 1/Tree 1: There are leaves on this tree, and no leaves on the other
Sign 2/Tree 2: There are leaves on one of these trees, but none on the other.
Exactly one of the signs is true, and the other is false. Which tree has leaves on (without looking)?
I'm starting to doubt that it's possible to tell, but I'm sure there's some logic that says otherwise!
