We have a game involving dice. It has 9 6-sided dice and each side of the dice has a unique picture on it, so there are 54 different pictures.

My son randomly grabbed a die, rolled it, and guessed what it would be. He guessed it would be a beetle, and it was.

What are the odds that he'd pick the right one? There are 54 different pictures, so I thought that it might be 1 in 54, but it seems like it is more incredible than that.
