The Monty Hall Problem

Pick a door!
Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the other doors, opens another door, say No. 3, which has a goat. He then says to you, ‘Do you want to pick door No. 2?’ Is it to your advantage to take the switch?

I’m going to say this only once. “Meridiem” means middle of the day. “Ante” means before and “post” means after. They’re all from Latin. The middle of the day, the meridiem, is noon. As in 12 noon. Ante meridiem (a.m.) is before noon. Post meridiem (p.m.) is after noon.
Noon is neither before nor after the middle of the day, neither a.m. nor p.m.: it’s exactly noon! Read more
