Grimm,
I'll make it VERY simple:
door #1 has goat behind it,
door #2 has goat behind it,
door #3 has BMW behind it.
THIS you know.
What you don't know is:
which door is which.
and you did NOT open the door on the first try,
you only indicated which door you want to be opened,
IOW,
you don't know what's behind the door you have chosen!

oh ok, so she did not open the door, just indicated.
this is boolean algebra.
1 goat
1 BMW
2 Doors
initially she had a 1/3 shot. 66% rate of failure.
doh this is easy
her shot remains the same. nothing has changed. She still has 3 doors, two goats, one behind each door. and a BMW behind the third. so instead of it being a 66% rate of failure by remaining the same. so she keeps her pick, er odds of failure reduce to 50%. 1/2 instead of 1/3. all the host did was show 1/3 of her failure options.\
is that correct?
