Moving Right Along: the Law of AND

Here's my concept for a very low-budget game show. First, the host picks the prize according to the table above, then he decides which of 3 doors to hide the prize behind. Then the contestant comes out and she picks a door. When she opens the door, either the room behind it is empty, or she has won a prize. Here's an example for ONE DAY:

Door 1 no prize!

Door 2 (3%) A tropical getaway!!!! OR (80%) a toaster OR (17%) a washer-dryer

Door 3 no prize!

 

Essentially when the contestant picks a door, she is hoping that the prize is behind that door AND that it's a tropical getaway (or maybe if she's an overworked Mom she's hoping its a washer-dryer, poor lady).
