The Monty Hall Problem

swap

At 0:21 he said booby...

here is why this is untrue: nce the first dor is open, the entire equation changes. S you cannt start uses elements from the first equation as sustitutes for the second. It's not 33 vs 66, after he opens the first door, it becomes 50/50.

Actually, your logic is not quit reasonable. You see, when you first picked a door chances were 66% vs 33%. But after that the game host reveals the door and you DONT swap you stick wit the same stakes since when you actually picked a door chances were 66% vs 33%. Now, if you DO swap the chance of getting a goat becomes: 66%* 50% or in equation form: 0.66*05= 0.33 or 33%. Hence, now you have got only one car and one goat, so the car gets 66% chance of being picked by you. :)

i try to get goat cuz in my country no gasoline for cars so goat much milk more and is good for meat and for ym faimily sorry bad ENglish.
