Puzzle – Russian Roulette

A horrific man is gambling Russian roulette with a six-shooter revolver. He places in a single bullet, spins the chambers, and fires at you, however, no bullet comes out. He offers you the selection of spinning again and firing, or just firing again without spinning. Should he spin once more?

Answer:

Yes, He should spin the chambers again before firing a second time. In a standard six-shooter revolver there are six chambers and after the first trigger pull with no bullet fired there is a 1 in 6 chance that the bullet is now in line with the firing pin. Spinning the chambers again increases the odds of not hitting the bullet on the second pull making it a safer choice. Always better to err on the side of caution in a game like Russian roulette.
