Question of the Day (29-Aug-19)
Jack is in a game show. The host shows him 100 doors, and tells him that there is a car behind one of them, and nothing behind the rest. Jack has to choose just 1 door, and he'll get whatever is behind it. However, after he makes his choice, the host opens 98 of the 100 doors, leaving closed the door that Jack chose and one other door. There is nothing behind any of the opened doors. Now, the host asks Jack whether he would like to stick to his original choice or switch to the other closed door. What is the probability that Jack will win the car if he switches to the other door?
