* In a game you may choose out of three options.

* One of the three contains a price, the others nothing

* After you choosed one, the moderator opens one of the others - an empty one, and asks you if you want to change your mind.

* What would you do: keep you current choice, or take the other one.

* You are allowed to create a program to calculate your changes :-)

* Please do that below
