WebThe cumulative distribution function (cdf) of the binomial distribution is F ( x N, p) = ∑ i = 0 x ( N i) p i ( 1 − p) N − i ; x = 0, 1, 2, ..., N , where x is the number of successes in N trials of a Bernoulli process with the probability of success p. The result is the probability of at most x successes in N trials. WebThe function: F ( x) = P ( X ≤ x) is called a cumulative probability distribution. For a discrete random variable X, the cumulative probability distribution F ( x) is determined by: F ( x) = ∑ m = 0 x f ( m) = f ( 0) + f ( 1) + ⋯ + f ( x) You'll first want to note that the probability mass function, f ( x), of a discrete random variable X ...
