context_page_description: Russian roulette is a highly lethal game of chance in which a player places a single round in a revolver, spins the cylinder, places the muzzle against their head, and pulls the trigger in hopes that the loaded chamber does not align with the primer percussion mechanism and the barrel, causing the weapon to discharge. Russian refers to the supposed country of origin, and roulette to the element of risk-taking and the spinning of the revolver's cylinder, which is reminiscent of a spinning roulette wheel.
  The deadly game is commonly associated with six-shot revolvers. If such is the case, mathematically, the average number of consecutive pulls of the trigger before the gun discharges is 3.5. After a single spin, the probability of it firing is 1/6, followed by 1/5 on the second pull, 1/4 on the 3rd pull and so on, until if it failed to fire 5 times, the probability is 1/1 on the final pull. If the cylinder is re-spun after each trigger pull, the probability of firing remains 1 in 6 on each occasion, and the probability of it having fired after 6 pulls is, or about 66.5%.
