You have a bucket of white wine and a bucket of red wine.
You take a cup of red wine and pour it into the bucket of white wine.
You mix it thoroughly.
Take a cup from the mixture and pour it back into the red wine bucket.
Is there more red wine in the white wine?
Or more white wine in the red wine?
See if you can work that one out. Two explanations and a few hours of thinking later and I still can’t get my head round it…
