You are captive of the Evil King in his dungeon!
The way out has 3 obstacles:
- There are 2 doors leading out of the dungeon. One door leads to a certain death.
The other one leads down a passage way.
- Down the passage way, a dragon lies sleeping!
Your probability of tip-toeing past the dragon is 3/10. (He eats you if you wake him up!)
- If you get past the dragon there is a fire pit. You must jump across it.
The probability that you successfully jump across the fire pit is 3/4.
If you do all this, you are free!
