I have read through around 10 articles and webpages on this problem, and still don’t understand. I’ve run simulations and yes, switching does get you better odds, but why?
In: Mathematics
They create bias with the door they select to show you. Imagine this
> The contestant has chosen door number 1. But lets look behind door number 2. Behind door number 2 is the grand prize that you can’t win any more. Do you want to keep the goat you know you have because of the process of elimination or switch to the other goat behind door 3?
That option never happens. It doesn’t happen. If you pick a goat they will always show you the other door with a goat. Its that bias that make your switch more likely to win an not 50/50
