The binomial distribution is a Bernoulli distribution for a single trial, i.e., when the value of n is 1. A Bernoulli trial or Bernoulli experiment is a single success/failure experiment, whereas a binomial process is a sequence of outcomes. The outcome of a single trial of an event is dealt with by the Bernoulli theorem, but the outcome of several trials of the same event is dealt with by the Binomial theorem. When the outcome of an event is required just once, Bernoulli is employed, but the binomial is used when the outcome is required several times.
