Three boxes are labeled 'Apples', 'Oranges', and 'Apples and Oranges', but every single label is currently incorrect. You are allowed to pull out just one piece of fruit from one box of your choice to figure out the contents of all three boxes. Which box should you pick?
The box labeled 'Apples and Oranges'
Since all labels are wrong, the box labeled 'Apples and Oranges' must contain either only apples or only oranges. If you draw a fruit from it (say, an apple), you know that box is the 'Apples' box. Since the box labeled 'Oranges' cannot contain oranges, it must contain 'Apples and Oranges', leaving the remaining box to be 'Oranges'.
