The document discusses using a normal distribution to approximate a binomial distribution. It provides examples of binomial distributions with different numbers of trials and probabilities of success, and asks whether those distributions can be approximated by a normal distribution. It introduces the concept of using a normal approximation to a binomial distribution and notes that the approximation gets better with a larger number of trials and a probability of success that is not too close to 0 or 1.
