You are stuck with a gangster who likes to play it rough. The only way to survive is to accept his invitation to play Russian Roulette.
He presents a revolver in which, three bullets have been placed consecutively. Now he spins the chamber cylinder of the gun. The cylinder wont be spun again. The gun will be passed between both of you till the gun fires and one of you is dead.

Let us label the chambers for our convenience as C1, C2... C6.
Now, when the cylinder is spun, there can be the following six outcomes.
1. If C1 is fired first: Player 1 dies.
2. If C2 is fired first: Player 1 dies.
3. If C3 is fired first: Player 1 dies.
4. If C4 is fired first: Player 2 dies (First shot, player 1, C4 empty. Second shot player 2, C5, empty. Third shot player 1, C6 empty. Fourth shot player 2, C1 not empty.)
5. C5 is fired first: Player 1 dies (First shot, player 1, C5 empty. Second shot player 2, C6, empty. Third shot player 1, C1 not empty.)
6. C6 is fired first: Player 2 dies (First shot, player 1, C6 empty. Second shot, player 2, C1, not empty)
Therefore, if you choose to go second, you have a 4/6 or 2/3 chance of winning.

#20 - House Distance Puzzle
In a town, there are four houses located at different distances from each other. Following are the distances:
The third house is 60 km apart from the first house.
The fourth house is 40 km apart from the second house.
The third house is 10 km nearer to the fourth house than it is to the second house.
Can you find out the distance between the fourth and the first house ?
75km
Distance between second and fourth house = 40 km
Distance between the second and third house + Distance between the third and fourth house = 40 km.
Distance between the second and third house + (Distance between the second and third house - 10) = 40 km.
Therefore,
2 * Distance between the second and third house = 50 km
=> Distance between the second and third house = 25 km
Hence, distance between the third and fourth house = 15 km
Distance between the first and fourth village = 60 + 15 = 75 km
