I'm throwing a big BBQ in my backyard, and I need some help gathering foodstuffs. By my calculations, I will need 8 tubs of ice cream to feed everyone for dessert, and I send you to the supermarket to purchase some. Coincidentally, the supermarket sells exactly 8 different flavors and has an abundance of each. If my only instructions are for you to return with exactly 8 tubs i.e. I don't care if you repeat flavors at the sacrificing of others, with how many different groupings can you possibly return?
