The Proof · Question 17 of 26

Should you take the sure 2 dollars, or open a box?

At the fair there's a stall where you can walk away with 2 dollars, guaranteed. Or you can open a mystery box: one box in three has 10 dollars inside, and the other two are empty.

What earns a point in this world: Asks where a claim came from, or says “I'm not sure yet”.

Take the sure 2!

Reasons a child might give

  • Two dollars I definitely have beats ten I probably don't.
  • Two times out of three I walk away with nothing.
  • I already know what I'm buying with 2 dollars.

Open the box!

Reasons a child might give

  • Ten is five times two. That's worth a go.
  • If I never take a chance, I stay where I am forever.
  • Nothing bad happens if I lose — I'm just back where I started.
