WebThe Binomial Random Variable and Distribution In most binomial experiments, it is the total number of S’s, rather than knowledge of exactly which trials yielded S’s, that is of interest. Definition The binomial random variable X associated with a binomial experiment consisting of n trials is defined as X = the number of S’s among the n trials WebNice question! The plan is to use the definition of expected value, use the formula for the binomial distribution, and set up to use the binomial theorem in algebra in the final step. We have E(e^(tx)) = sum over all possible k of P(X=k)e^(tk) = sum k from 0 to n of p^k (1-p)^(n-k) (n choose k) e^(tk)
