Case Study Prompt

You are a contestant on a game show.

There are 3 doors: A, B, and C. Behind one of them, there is a car.

Your job is to determine which door is the most likely to be hiding the car.

First, you pick 1 door. For example, you pick door A. 

Then the game host will open one of the other 2 doors that does not have car, for example, door B. Now you have a choice to change your mind, to pick door C. Or you can stick to your first choice of door A.

Would you change your choice?
