Now we differentiate … WebSo E[X] = r/p, and Var(X) = r(1−p)/p2. 5 Poisson random variables Think about a very large number of Bernoulli trials, where n → ∞, but the expected number of successes stays constant, say λ. For instance, suppose we’re looking at the number of particles emitted by a chunk of radioactive substance
