Cumulative probability mass function
WebCumulative Required. A logical value that determines the form of the function. If cumulative is TRUE, then BINOMDIST returns the cumulative distribution function, which is the probability that there are at most number_s successes; if FALSE, it returns the probability mass function, which is the probability that there are number_s successes. Web14.6 - Uniform Distributions. Uniform Distribution. A continuous random variable X has a uniform distribution, denoted U ( a, b), if its probability density function is: f ( x) = 1 b − a. for two constants a and b, such that a < x < b. A graph of the p.d.f. looks like this: f (x) 1 b-a X a b. Note that the length of the base of the rectangle ...
