However, as n gets larger, a binomial distribution starts to appear more and more normal and each one is a good approximation for the other. Geometric Experiments - experiments having all four conditions: 1. WebThe mean, μ, and variance, σ2, for the binomial probability distribution are μ = np and σ2 = npq. The standard deviation, σ, is then σ = n p q. Any experiment that has characteristics two and three and where n = 1 is called a Bernoulli Trial (named after Jacob Bernoulli who, in the late 1600s, studied them extensively). pool chlorine poisoning symptoms
