Bernoulli and Binomial Random Variables

Bernoulli and Binomial random variables are key building blocks for more sophisticated distributions, such as the Normal and Poisson distributions. A Bernoulli random variable takes one of two values, like a coin flip. A Binomial random variable is constructed by repeating several Bernoulli random trials; for example, if we flip 10 coins, the number of heads is a Binomial random variable.
