Imagine we have 3 identical boxes. In one of the boxes are red balls, in another are green balls, and in another, there are both red and green balls. Matt writes labels and puts them on the boxes: Box 1 gets the label RED, Box 2 gets GREEN, and Box 3 gets RED AND GREEN. Unfortunately, the boxes were rearranged before he put on the labels, and each label has been incorrectly placed! If he reaches into box 3 and pulls out a red ball, which box has only green balls?

*Keep in mind that ALL labels are wrong*

 

1. We know that the box with only green balls can't be Box 3 since Matt pulled a red ball from there.

 

2. Box 2 also can't be the box with only green balls because it's labeled GREEN, and the label is supposedly wrong.

 

3. We have one choice left, Box 1!

 

Answer: Box 1 smiley
