Arnold has a revolver which holds up to six bullets. There are two bullets in the gun, in adjacent chambers. He decides to play Russian roulette (on his own!). He first spins the cylinder so that he does not know where the bullets are and then pulls the trigger.
Assuming that Arnold survives this first attempt, is he now better off pulling the trigger a second time without spinning the cylinder again or would he be better off spinning the cylinder again before pulling the trigger?
