oh my god this is old as shit.
People still don't know this ? I thought this is getting teached in every school by now...
Just look what richardhutnik posted and it's veeeery easy to understand.
Let there be a million doors and one of them has the prize in it. Pick one, your chances to win are 1/1000000 at the moment. The host closes every other door except for 2, naturally there is only the one you picked at the very beginning left and a second one.
Your door STILL has the probability of 0,000001%, thus the other door IS in 999999 cases the right one.
