Three boxes are labeled: 'Apples', 'Oranges', and 'Apples and Oranges'. Every single box is labeled incorrectly. You are allowed to draw only one fruit from one box to fix all the labels. Which box do you choose to draw from?
The box labeled 'Apples and Oranges'
Since every box is labeled incorrectly, the box labeled 'Apples and Oranges' cannot actually contain both. Therefore, it must contain entirely apples or entirely oranges. By drawing one fruit from this box, you instantly know its true contents. Using that information and the mislabeled nature of the other boxes, you can correctly deduce the rest.
