A popular television game show, Let’s Make a Deal, from the 1960s and 1970s featured a new car hidden behind one of three doors, selected at random. Behind the other two doors were less appealing prizes (e.g., goats!). When a contestant played the game, he or she was asked to pick one of the three doors. If the contestant picked the correct door, he or she won the car!

A twist!
Now consider a fun twist that the game show host adds to this game: Before revealing what’s behind your door, the host will first reveal what’s behind a different door that the host knows to be a goat. Then the host asks whether you (the contestant) prefer to stay with (keep) the door you picked originally or switch (change) to the remaining door.
