Binomial and geometric random variables
WebJul 31, 2024 · We know that Bernoulli distribution where f ( k) = p k ( 1 − p) 1 − k is the frequency function for number of successes in a single trial (??). We also know that the geometric dirtribution models the number of failures up to the first success. Wouldnt be the frequency function for the random variable just be the geometric distribution with ...
