[Project] The Monty Hall Problem
Recently I watched this Youtube video ( The Monty Hall Problem )
“Put simply: If you pick a goat then swap you will always win the car. And you have a 2/3 probability of picking a goat.”
I was so amazed by this logic and static thinking problem.
I use PowerShell to write this The Monty Hall Problem prove program and as yo can see from the program result screenshot,
there is very high chance you get a car when you swap your answer.
just for fun and for practice 🙂
