Captain Holt: It's the "Monty Hall problem." Imagine you're on a game show. There are three doors, behind one of which is a car.
Kevin: You're telling it wrong. There are three doors, behind one of which is a car. You pick a door. The host, who knows where the car is, opens a different door, showing you there's nothing behind it. Now the host asks if you'd like to choose the other unopened door. Should you do it?
Captain Holt: No.
Kevin: Yes.
Both: It's simple math.
Captain Holt: It doesn't make any sense to switch. The prize is behind one of two doors. It's a 50/50 chance either way.
Kevin: It's 2/3 if you switch, 1/3 if you don't. The probability locks in when you make the choice. We've been over this eight times.
Captain Holt: Seven times. Now you can't even do simple addition.
Amy: Kevin is right.
Captain Holt: Hmm. You're fired.
Amy: What?
Rosa: Ah!
