It never ceases to amaze me the thinking processes people go through to arrive at the wrong answers. A response to the second coin problem stated the following: case 1) top=g bot=g top=g bot=s top=s bot=s case 2) top=g bot=g top=s bot=g top=s bot=s "If a gold coin is found in the bottom drawer in case 1, a gold coin will be in the top drawer 100% of the time. If a gold coin is found in the bottom drawer in case 2, a gold coin will be in the top drawer 50% of the time. Since both cases are equally likely: .50(1)+.50(.5)=.75 " ***************************** NOT TRUE ******************************* Since case 2 has more gold coins in the bottom drawers, this case occurs more often. Exactly twice as often. Hence: .33(1)+.67(.5)=2/3 !! Next time dont let anyone talk you out of the correct answer which is and always will be 2/3.
