[QUOTE="Blacksad, post: 352465, member: 1359"] [B]You[/B] made a mistake, if you roll a 20, your chance of your next roll to be a 20 is still 1/20, the answer is indeed 50% for each case. If you want a confusing issue, here is another problem for your players: An evil king asks his wizard to brew a potion of longevity. The equally evil wizard decide to brew 3 potion, two of black lotus extract and one of longevity, and propose a little game to the king. The king chose potion number 1, and the wizard say that the king was right to not chose potion number 3, then the king change his mind and take potion number 2. Why? Well Because you have higher odds with the other, the possibilities are as follow: when the king chose one potion it has 1/3 chances of being the one of longevity. so we have 1/3 the king chose the potion of longevity, change his mind and die. and 2/3 the king chose the wrong potion, the wizard show the other wrong, and the king chose the one of longevity.
