Riddle: You are on a game show and you have a chance to win a car. There are three doors. Two contain goats while the one contains a car. You choose a door and the host opens up another door to reveal a goat(the host knows where the car is). After he shows you a goat, he gives you one last chance to change what door you want to select. Should you stick with the door you picked or switch your door? Also, what is the probability of getting the car for your answer?
Answer: You have a 2/3 chance of getting the car if you switch.
