Still confused on how the contrapostive of this makes sense?
"If a window does not contain purple glass, then that window contains orange glass."
Isn't it possible that the Glass contains no orange and no purple? I understand this would be impossible based on the other rules. Namely that y,g,r can't be together. But how does that make sense on its own? Thanks
