Why does the probability “lock in” and not change if you remove a variable but doubles for the other one?
I read it multiple times and it still doesnt make any logical sense to me.
In: Mathematics
When they reveal one of the doors and ask if you would like to switch, the probability doesn’t become 50/50 because they aren’t asking you what door the goat is behind.
Instead they are asking you if you believe you picked right in the beginning.
Because there were 3 doors, you had a 1/3 chance of getting it right (staying) and a 2/3 chance of getting it wrong (switching)
