The probability that a given set of ki individuals is infected equals the probability that a given set of St – ki individuals remain susceptible equals . The probability of the given set of ki individuals being infected and the given set of St – ki individuals remaining susceptible equals the product of these two probabilities, i.e. .

The number of ways of choosing ki out the St susceptible individuals to become infected is given by the binomial coefficient , which can also be written as .

The overall probability of ki out of the St susceptible individuals being infected is therefore given by the equation:
