Lucky Charms cereal has four marshmallow shapes: mallard, white, brown, and daffy. For historical reasons, they throw huge, equal quantities of each shape into a giant vat at the beginning of the day, and mix up the vat. Then, they measure out 16 marshmallows into each little box of cereal.

I assume the question is, given a sufficiently large source of marshmellows that we should consider the source infinite for the sake of the problem--what is the probability that exactly four of the 16 marshmallows in a box of cereal are mallards, given that 1/4 of the marshmallows from the source are mallards?
Find Probability(4 mallards | 16 marshmallows).
Prob = C(16,4) * [(1/4)^4] * [(3/4)^12] = 0.225199
