Binomial distribution, along with normal distribution, plays an important role in school mathematics. However, in all reality, students rely simply on memorization even for its simple properties such as average or variance therefore most students struggle to study binomial distribution and its applications. Although there are difficulties in studying binomial distribution, since it plays a vital role in increasing problem solving skills and mathematical balance in real life, one cannot neglect studying this subject. In this paper we suggest a program that shows various graphical illustrations of binomial distributions. The developed program could be contributes to not only increasing the student’s interest but a simulator for combined binomial distributions.
