Unformatted text preview: five conditions are met: (1) there is a series of N trials; (2) on each trial, there are only two possible outcomes; (3) on each trial, the two possible outcomes are mutually exclusive; (4) there is independence between the outcomes of each trial; and (5) the probability of each possible outcome on any trial stays the same from trial to trial. When these requirements are met, the binomial distribution tells us each possible outcome of the N trials and the probability of getting each of these outcomes....
