Binomial pdf and cdf
WebThe probability mass function for binom is: f ( k) = ( n k) p k ( 1 − p) n − k. for k ∈ { 0, 1, …, n }, 0 ≤ p ≤ 1. binom takes n and p as shape parameters, where p is the probability of a single success and 1 − p is the probability of a single failure. The probability mass function above is defined in the “standardized” form.

WebJul 11, 2014 · For me the pdf gives the whole probability to a certain point (basically the area under the probability). The pmf give the probability of a certain point. The cdf give the probability under a certain point. So to me the pdf and cdf have the same information, but the pmf does not because it gives the probability for a point x on the distribution.
