If it's kinda hard for you guys, split the calculation into three events and then count each event separately, starting at the branch for the first event, then branching for the next event, then branching for the last event (unless this is the single shot event). Then, once you have done this for all possible scenarios, add them up. Your check is adding them all up together and getting 1.
