really basic trick, I'm quite tired and can't wrap my head around how it works out to 2/3 chances
A contestant on a quiz show is asked to choose one of the three doors. Behind one of the 3 doors is a lady. But behind the others is a toy doll.
The contestant chooses one of the 3 doors.
The host opens one of the remaining two doors and reveals a toy doll. The host then asks the contestant if they want to stick with their original choice or switch to the other unopened door.
State what you would recommend the contestant to do in order to have the greatest probability of choosing the door with the lady. Show working!
