In my opinion, undoubtedly, the best option is to change the choice. If I pick a goat at first time, there is only one goat the host can reveal. So, the host opens the only other goat door and then I swap to the remaining closed door the car. So, the probability of winning a car by changing my choice is of 74%, and of winning a goat is 26%. If I keep my choice, it doesn’t matter which other goat door the host opens, because I am sticking with my first choice and the chance that I have already picked the car is 40%, and the chance I have already picked a goat is 60%.
It’s better to change the door, cause if you see the video explaining the Monty Hall Problem: (https://www.youtube.com/watch?v=mhlc7peGlGg), it explains why if you choose the other door, he other door, your probabilities are higher than if you keep it, as seen in my experiment.
