![]() ![]() Unfortunately, the Monty Hall problem does not satisfy either requirement. However, for this method to produce the correct answer, the process you are studying must be random and have probabilities that do not change. ![]() That’s why it feels so right that the final two doors each have a probability of 0.5. The probability of a heads is 0.5 and we obtain that simply by dividing the specific outcome by the total number of outcomes. Typically, we think of probabilities for independent, random events. Our brains are using incorrect statistical assumptions for this problem and that’s why we can’t trust our answer. To understand the solution, you first need to understand why your brain is screaming the incorrect solution that it is 50/50. The tough part is to understand why this happens! I hope this empirical illustration convinces you that the probability of winning doubles when you switch doors. Why the Monty Hall Solution Hurts Your Brain The final row shows the total wins and it confirms that you win twice as often when you take up Monty on his offer to switch doors. We just need to count up the number of wins for each door strategy. The table shows all of the potential situations. If you switch from door 1 to door 2, you win. ![]() Monty can only open door 3 because otherwise he reveals the prize behind door 2. For this scenario, if you switch you lose or, if you stick with your original choice, you win.įor the second row, you pick door 1 and the prize is behind door 2. Because neither closed door has the prize, Monty is free to open either and the result is the same. The first row shows the scenario where you pick door 1 initially and the prize is behind door 1. Each row shows a different combination of initial door choice, where the prize is located, and the outcomes for when you “Don’t Switch” and “Switch.” Keep in mind that if your initial choice is incorrect, Monty will open the remaining door that does not have the prize. Here’s how you read the table of outcomes for the Monty Hall problem. Therefore, I can just show them all to you and we calculate the percentage for each outcome. It turns out that there are only nine different combinations of choices and outcomes. Since it’s a very limited time, the developers have to make up for the lack of it by employing the best of their creativity and thinking of innovative ways to make it happen.It’ll probably be hard for me to illustrate the truth of this solution, right? That turns out to be the easy part. Probably the most fun and challenging part of the event is the time slot given for contestants-48 hours to create a game from scratch. Before that, the topic is held secret, so it’s really only at the event that the participants will know it. “Global Game Jam is an international event for game developers and enthusiasts where the participants create a video game based on the topic disclosed before the event’s beginning. Since it might be that you are hearing about this event for the first time, we’ve asked Gediminas to tell us a bit more about it. Now, we heard it through the grapevine that this Association was responsible for the Lithuanian branch of Global Game Jam. To make this article even better, we’ve talked to Gediminas Tarasevičius from the Lithuanian Game Developers’ Association ( Lietuvos Žaidimų Kūrėjų Asociacija), who has so kindly answered a couple of our questions on video and arcade games. ![]()
