Some people need a math lesson.

18. Yeah, I know, not a great math example

With only three doors it does seem counter intuitive. And with only three doors it would be possible to have quite a run of luck always sticking with the same door. I guess the part that blew my mind was when I switched the example to be based on 100 doors. As I mentioned in my post my friend was still convinced it was a 50-50 proposition even starting with 100 doors. By that logic you could show somebody 1 million doors and ask them to pick one and then eliminate all the other doors but one. According to my friend it would still be a 50-50 chance to stick with the door you originally picked or switch to the only remaining other door out of 1 million. That’s what I meant when I said some people have a very questionable understanding about math and probability.
