I just heard this one and I can't decide:
You're in a game show, and there are 3 doors to pick from.
One has a car behind it, and the other two just have lumps of coal.
You get whatever is behind the door you pick, and you want a car!
You pick one. 2. The game show pauses for an advertisement, then resumes.
To make the show more suspenseful, the host opens a door (that you didn't pick) 1
and you see that there is a lump of coal behind it. He then gives you the opportunity to switch.
What do you do? Do you switch to door 3, or stay with door 2????
Bolded text is example.
