I have ordered ten of the LEGO Super Mario character packs from the LEGO store online.
I would expect that the models in these packs to be distributed randomly, i.e. each pack has a 1-in-10 chance to include each of the ten models. However, having opened eight of the ten packs, I have received eight distinct models (I am only missing the bullet-bill and the Fuzzy).
The chances of this happening by random chance are small - I'm not 100% sure on the mathematics, but I think its about 1,8%.
Does anyone know if the (online) LEGO store systematically tries to make sure customers do not get repeats in random packs?
