Lets play a game of Russian roulette. 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 ?
Solution below...
shoot without spinning. if the barrel is spun, the chance of being shot is 2/6 = 1/3. if it is not spun, there is only one position out of 4 that would lead to being shot, so that chance in this case is 1/4.
since 1/4
