There is a certain set of values for each chest that determine these values, known as rarity factors. These values can be found here: Template:CardChance/Data.

To determine the rare/epic odds, simply take the number of cards in the chest and divide it by the appropriate rarity factor. Once this quotient is obtained, the integer part represents the number of guaranteed cards of that rarity, while the decimal part represents the chance of getting another card of that rarity. For example, if the quotient obtained when calculating number of epics is 1.5, it means that the chest guarantees 1 epic and has a 50% chance of containing another.
