When combining "probability" and "number" a vehicle will be emitted randomly with the given probability each second until the specified number is reached. Thus the end time of the flow is itself a random variable. The end time of the simulation can only be used to end this process prematurely. If you need a fixed number of vehicles, randomly distributed in a fixed time frame, either - use duarouter with option --randomize-flows to preprocess your route files (use flows specified with 'end' and 'number') or - generate your traffic with randomTrips.py using option --random-depart ( https://sumo.dlr.de/docs/Tools/Trip.html#insertion_distribution)
