You are tied to a chair and can,t get up.Here is the gun , six chambers all empty. Now I put two bullets in the gun and I put these bullets in the adjecent chambers. I close the barrel and spin it. I put the gun to your head and pull the trigger. Clik and the slot was empty. Now before we start the interview I want to pull the trigger one more time , which one do you prefer , that I spon the barrel first or that I just pull the trigger ?
X being a bullet, _ being and empty chamber. The gun rotates from 1 to 6, and the bullets are in adjacent chambers.
The setup: _ X X _ _ _
1 2 3 4 5 6
The interviewer just got a blank, so the current position must be 1,4,5, or 6. If it’s 1, the next one is a bullet. If it’s 4-6, the next one is empty. So if the interviewer just fires again, you have a 1/4 chance of getting shot.
If, on the other hand, the interviewer spins again, you’re back to the initial 2/6 or 1/3 chance of getting shot.
I’ll take the 1/4 chance, myself.
