The binomial distribution is appropriate when we have a discrete number of trials (in this case, choosing 10 students) and each trial (choosing a student) has only two possible outcomes (prefer Coca-Cola or not). Additionally, the probability of success (preferring Coca-Cola) is fixed and constant (at 0.6) for all trials. Therefore, the binomial distribution is the best choice for this scenario.
