MM2: Expected numbers of copies of a card

Modern Masters 2015 has the same rarity distribution as Khans of Tarkir: 101 commons, 80 uncommons, 53 rares, and 15 mythics. However, each pack also has a foil card. According to some sources, a box typically has about 16 foil commons, 6 foil uncommons, and 2 foil rares (presumably 1/8th of which are mythics). This means that an 8-person MM2/MM2/MM2 draft will have an average of 2.5 copies of a given common, 1.0 copies of a given uncommon, 0.4 copies of a given rare, and 0.2 copies of a given mythic.
