• The Binomial Distribution: Exactly k Successes in n Trials

  Find the probability of exactly k successes in n independent trials with the binomial formula, see why it works, and answer at least and at most questions.

• Random Variables and Expected Value

  How a random variable turns outcomes into numbers, how to build its probability distribution from theory or from data, and why expected value is the long-run average.
