A Bernoulli Trial or Binomial Trial is an experiment in which there are exactly two possible outcomes: Success or Failure.
A random variable is assigned with: Success = 1 and Failure =0.

**Important:**A Bernoulli Trial is completely determined, i.e. we know EVERYTHING about it, if we know the p= probability of Success= Pr(1).
