    This function has these arguments:

    Argument Description
    x An integer representing the number of failures in trials
    r An integer representing the threshold number of successes
    p Probability of success on each trial A number between 0 and 1
    cumulative A logical value that determines the form of the function. If cumulative is TRUE, this function returns the cumulative distribution function; if FALSE, it returns the probability density function
