In a binomial distribution, the variable X is discrete, not continuous. The probability of the event of interest is stable from trial to trial, which is why it is called a "success probability." There is no specific requirement for the number of trials n to be at least 30. The results of one trial are independent of the results of the other trials, which is what makes this distribution binomial. Therefore, the best choice is B.
