Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?
To the surprise of most people the probability of winning is not 50/50 but 2/3 to 1/3 in favor of switching. I know you won't believe this therefore you can use this application to test it yourself. Either play it yourself with whatever strategy you want or watch the simulation and see how the statistics evolve.In case you wonder, the simulation is based on pure random choices of the doors. There is no hidden algorithm or sneaking involved.
