Parabola needs to catch a train. The train arrives randomly some time between 1:00 and 2:00, waits for $10$ minutes, and then leaves. If Parabola also arrives randomly between 1:00 and 2:00, what is the probability that the train will be there when Parabola arrives?
This problem is extra hard, so the correct answer gets $20$ PP.
