There are 1 billion boxes. 1 billion of these boxes have a bomb in them, apart from 1 box which has your deepest desires.

If you open a box with a bomb, the bomb goes off and you die. If you open the box with your deepest desires, they will be fulfilled.

You select a box at random.

The gamemaster reveals 999,999,998 boxes that have have bombs in them of the 999,999,999 other boxes that you didn't pick and disarms the bombs.

There are only 2 boxes left - the box you selected at random at the start, and the one the gamemater has not opened.

Which box do you open?
