      Probability Formula for a Binomial Random Variable Often the most difficult aspect of working a problem that involves the binomial random variable is recognizing that the random variable in question has a binomial distribution. Once that is known, probabilities can be computed using the following formula.

      The 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

      In a binomial distribution the probabilities of interest are those of receiving a certain number of successes, r, in n independent trials each having only two possible outcomes and the same probability, p, of success. So, for example, using a binomial distribution, we can determine the probability of getting 4 heads in 10 coin tosses.
