    Binomial Probability Distribution

    This calculator computes P(a \(\leq\) x \(\leq\) b), where x is a binomial random variable, and a and b are the lower bound and the upper bound for x respectively.  Please report the error to Dr. Jessica Kuang at

    To learn how to use this calculator, watch a short video here.


    Enter the lower bound and the upper bound for the number of successes, the number of trials (\(n\)), and the probability of success (P), and then hit Calculate.

    Lower Bound:   Upper Bound:   \(n\):   P (enter a decimal):
