- I've made up another problem, similar to the Monty Hall problem. The
- similarity is very obvious, but it does give it a different twist,
- though.
-
- Disclaimer: First, I have been reading this group for just two days, so
- excuse me if a similar extension has already been posted.
- Second, I don't claim this to be a smart problem (what do you expect ;-)).
-
- There are five doors, behind two of them a car, and behind each of the
- other three doors a goat. You pick a door and the quizmaster (who knows
- what's behind the doors) opens a door with a goat behind it.
- 1) Should you change doors?
- 2) Why is the sum of the probability of changing and not changing not
- equal to one?
-
- Happy Fireworks!
