Web4.3 Binomial Distribution. There are three characteristics of a binomial experiment. There are a fixed number of trials. Think of trials as repetitions of an experiment. The letter n denotes the number of trials. There are only two possible outcomes, called "success" and "failure," for each trial. The letter p denotes the probability of a ... WebThe outcomes of a binomial experiment fit a binomial probability distribution. The random variable X = the number of successes obtained in the n independent trials. The mean, μ, and variance, σ 2, for the binomial probability distribution are μ = np and σ 2 = npq. The standard deviation, σ, is then σ = n p q n p q.
