Nick, Kurt, and Dale head to Rex Hansen’s house with a plan to kidnap him and hold him for ransom to pay for a past business deal gone awry. When they get to the door, Kurt and Dale try to open it, but are surprised to find it locked because they believed the probability of it being locked was only 50/50. While there are only two possible outcomes, it doesn’t mean the probability of each outcome is the same.

This concept has been mistaken in other shows like Corner Gas and Young Sheldon.
