You are on a game show. There are three doors, behind one of which is a
prize and the other two is a chunk of coal, and the host knows which door
holds the prize. You choose door #1. Before it is opened, the host opens
door #3 and reveals a lump of coal. You have the choice to stick with the
door you chose originally or switch to door #2. What do you do? | p*********9

depends on if the host wants you to get the prize, which is why host opens
this door.
