The binomial model is the best choice because it describes the probability of a fixed number of successes (sales) in a fixed number of trials (calls) when the probability of success is constant. In this case, we are interested in the probability of making exactly 2 sales in 20 calls, and we assume that the probability of making a sale is the same for each call.
