The document discusses using the Poisson distribution to approximate a binomial probability. Specifically, it involves using the Poisson distribution to approximate the binomial probability b(3; 100, 0.03), which represents the probability of exactly 3 successes in 100 Bernoulli trials with a probability of success of 0.03 in each trial.
