what are the chances of dying in russian roulette
Russian roulette Because only one chamber is loaded, the player has a one in x chance of being shot; x is the number of chambers in the cylinder. So, for instance, if a revolver holds six chambers, the chance is one in six. That assumes that each chamber is equally likely to come to rest in the "correct" position. However, due to gravity, in a properly maintained weapon with a single round inside the cylinder, the full chamber, which weighs more than the empty chambers, will usually end up near the bottom of the cylinder when its axis is not vertical, altering the odds in favor of the player.[citation needed] This only applies to swing-out cylinder type revolvers, and only if the cylinder is spun outside of the revolver and allowed to come to a complete stop before being locked back in.[citation needed] The number of pulls of the trigger before a round is expected to discharge is 3.5 (without spinning between the pulls) or 6 (with spinning between the pulls).[1]
Klondike (solitaire) For a standard game of Klondike, drawing three cards at a time and placing no limit on the number of re-deals, the number of possible hands is over 7067800000000000000♠8×1067, or an 8 followed by 67 zeros. About 79% of the games are theoretically winnable,[3] but in practice, human players do not win 79% of games played, due to wrong moves that cause the game to become unwinnable. If one allows cards from the foundation to be moved back to the tableau, then between 82% and 91.5% are theoretically winnable.[4] Note that these results depend on complete knowledge of the positions of all 52 cards, which a player does not possess. Another recent study has found the Draw 3, Re-Deal Infinite to have a 83.6% win rate after 1000 random games were solved by a computer solver.[5] The issue is that a wrong move cannot be known in advance whenever more than one move is possible. The number of games a skilled player can probabilistically expect to win is at least 43%.[3] In addition, some games are "unplayable" in which no cards can be moved to the foundations even at the start of the game; these occur in only 0.025% (1 in 4,000) of hands dealt.[6][7][8]
