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 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 switch your choice?

Yeah I've seen this puzzler before, your odds are better if you switch, whether it's three doors or a million.

Why did he open door #3 when I specifically requested door #1? ðŸ˜

All three doors are a win. Before your choice you had nothing.

No.
You have more chance of winning the goat if you stay put.
