I did a little more research, and this is what I came up with.
Quote:
If an event occurs N times (for example, a coin is flipped N times), then the binomial distribution can be used to determine the probability of obtaining exactly r successes in the N outcomes. The binomial probability for obtaining r successes in N trials is:
where P(r) is the probability of exactly r successes, N is the number of events, and (pi symbol) is the probability of success on any one trial. This formula assumes that the events:
(a) are dichotomous (fall into only two categories)
(b) are mutually exclusive
(c) are independent and
(d) are randomly selected
