    • A Bernoulli process is a finite or infinite sequence of independent random variables X1X2X3, ..., such that
      • For each i, the value of Xi is either 0 or 1;
      • For all values of i, the probability that Xi = 1 is the same number p.
    • In other words, a Bernoulli process is a sequence of independent identically distributed Bernoulli trials.

      Independence of the trials implies that the process is memoryless. Given that the probability p is known, past outcomes provide no information about future outcomes. (If p is unknown, however, the past informs about the future indirectly, through inferences about p.)

      If the process is infinite, then from any point the future trials constitute a Bernoulli process identical to the whole process, the fresh-start property.

    • BERNOULLI TRIALS: Many experiments consist of a sequence of trials, where
      • (i) each trial results in a “success” or a “failure,”
      • (ii) there are n trials (where n is fixed),
      • (iii) the trials are independent, and
      • (iv) the probability of “success,” denoted by p, 0 < p < 1, is the same on every trial.
    • TERMINOLOGY : In a sequence of n Bernoulli trials, denote by X the number of successes (out of n). We call X a binomial random variable, and say that “X has a binomial distribution with parameters n and success probability p.” Shorthand notation is X ~ B(n, p).
