I have a homework problem where I have to state if an argument is valid, conclusive or neither. However I am struggling to wrap my head around this one.
The argument goes:
Generally, a flood occurs only if there is too much water. Yet a flood is occurring, although there isn't too much water. So a flood isn't occurring.
I am having difficulty as the premises states that there is a flood occurring, however then the conclusion states that there is not.
So far I have attempted this method:
F: There is a flood occurring W: There is too much water W -> F F && ~W Therefore ~F
However I am not too sure what to make of that.
Can the premises just be wrong like that and the argument still be valid?
