You are a contestant on a game show. There are three curtains. Behind one of the curtains is a new car. You are asked to choose one of the curtains. Lets say that you choose curtain #1. The host of the show - who knows where the car is so as not to end the game prematurely - opens curtain #3 and of course there is no car behind it. The host now gives you a choice. You can stay with curtain #1 or you can change your choice to curtain #2. The question now is: would it be to your advantage to stay with curtain #1, or would it be to your advantage to change to curtain #2 or would there be no advantage either way?

Change to Curtain 2. The odds were that you selected wrong initially (1:3) and since you know the right choice remains it is more likely the curtain you didn't choose.

What would you do if after your pick of curtain #1, and before any curtain was opened, the host told you that you could switch to BOTH curtains 2 and 3?
I have chosen Curtain #1 out of 3 choices, a 33 1/3 probability of being correct...
I then have a 50/50 chance at staying with curtain #1, or taking another 50/50 chance on Curtains #2 and #3?"Neighbor, how long has it been since you’ve had a big, thick, steaming bowl of Wolf Brand Chili?”

Put down beans and cross out cake,
Let me see, oh dear me.
What a task to undertake,
Milk plus bread, oh my head!
Add, subtract and multiply,
Till you're overcome;
This is much too hard for me,
I can't do the sum!
