Logic puzzle: under which hat is the ball?

Watch the video: logic puzzle: under which hat is the ball?

The claims:
Number 1: The ball is under this hat.
Number 2: The ball is not under this hat.
Number 3: The ball is not under hat 1.
In which hat is the ball you are looking for? Remember, only one statement is true.
(giving time)
Here is the resolution:
If the ball were under hat 1, then claims 1 and 2 would be correct. However, there is only one true claim. The ball cannot therefore be under hat 1.
How about hat 3? If the ball were under hat 3, then there would also be two assertions: assertions 2 and 3.
So: only hat 2 remains.
This means that only the third assertion, namely “The ball is not under hat 1”, is correct.
