WebMay 21, 2024 · Binomial Trials. There are a fixed number of independent trials n. Each trial has only two (hence binomial) outcomes, either “success” or “failure”. For the trials, the probability of success, p is always the same, and the probability of failure, q = 1 − p, is also always the same. The expected value E ( X) = n p. Webwith one trial and can be used to simulate Yes/No or Success/Failure conditions. This distribution is the fundamental building block of other more complex distributions.
