Did you know that M&M's have a relatively set amount per year? I believe it's not exact (I'm really not sure) but it's not random. And each year they change the set amount. Let me give you an example on a small scale. One year they could choose that the amount of red will be 4 of 10 M&M's, orange will be one, brown will be one, blue will be two, yellow will be one and green will be one. The next year they could choose it to be that Red - 2, Orange - 1, Yellow - 3, Green - 1, Blue - 2, Brown - 1.
