Tbh I ' ve only seen clips of it after I gave up watching the first episode after Ferrari started shouting at someone for disagreeing with him . He seems to think the voice of London character from V for Vendetta is someone to be emulated . <| sep |> No worries gl <| sep |> you realize the still frames I took where from exactly the moment I fired ? Which is the reason why the white circle is there in the first place . If I missed , the circle would be drawn on the wall , not on the head . I fired at 000749 , not 000753 . <| sep |> I have to wait for more than 1 minute only if all 10 tables rolled 1 % case . My reasoning is that Emini remainingTimeOnTablei leq Emini unavailableTimeOnTablei 10 . 01 1 0 . 01 7401 leq 1 0 . 018 . The first term clearly dominates , so I would guess that the value is about 111 . I ' m guessing that what problem is trying to say is to assume that unavailability time is same for all 10 tables , and that the average time for that identical time is 75 minutes . In that case , the expectation will simply linearly carry through so the answer to the riddle would be 7511 minutes . But that model seems unnatural .
