An elementary analysis of the probability that a binomial random variable exceeds its expectation
Abstract
h i g h l i g h t s • An elementary lower bound of the probability that a binomial random variable exceeds its expectation. • Stronger than most previous bounds. • Yields a still elementary proof for the fact that this probability is at least 1/4 when p is at least 1/n.
