There are Anna and Berta that needs balls for their Christmas trees. If a 'special arrangement of the balls" is necessary, wouldn't that mean that we couldn't in fact have a randomly ordered sequence after all? I contend (again, without a rigid mathematic proof, 'cos I'm not that bright) that you can't actually arrange the balls specially to 'guarantee' that both Anna and Bertha get their required proportions of Christmas baubles. In saying that, it does appear that in a very small number of sequences, you can actually get a clear run of 70 that matches the criteria, and thereby the remainder would also match the criteria, but only when glommed together into a line; but it's a fairly small percentage of chance.
