Once you choose a box, theres a 50 percent chance that youll get a gold ball (three gold and three silver balls). Picking a gold ball out of the box that you chose eliminates the box that has zero gold balls from the equation. Exactly. You had to have chosen the right box first so that probability cannot be ignored. The 1/3 it takes will take priority and therefore change the outcome of the last gold ball so 16 2/3% total. --- https://imgur.com/ARaZB2G https://imgur.com/LvEUiSl <cite>MelzezDoor posted [p:905501353] in IQ Test...
