Poisson distribution is used for counting the number of events occurring randomly over a fixed time period, given the average rate of occurrence. Since the number of births of twins may occur randomly during a 24-hour period and their occurrence rate is relatively rare, Poisson distribution is the best model. The other options, including binomial, hypergeometric, and uniform distributions, are not appropriate in this context because they require a specific number of trials, a fixed population size, or a continuous outcome, which do not fit the scenario of twin deliveries in a hospital.
