Fine, how about some simple statistic problems?
A trainload of unnamed consoles are set to arrive at a distribution center between 8 and 8:10PM. It is now 8:03PM and the train still has not arrived. Assuming the train will arrive in the designated window, what is the probability it will arrive within the next minute? What if it's 8:07PM and the train has still not arrived, what is the probability it will arrive within the next minute?
Say the same unnamed console has a failure rate of 1/10 within the first 15 minutes of being powered on. If there is a stack of 20 of these consoles and 8 have already been picked, tested for 15 minutes, and passes, what is the chance the one you pick will fail within the 15 minutes of being powered on?
