The video tutorial covers the normal approximation of the binomial distribution, explaining Bernoulli trials and their properties. It demonstrates how to calculate probabilities in binomial experiments and introduces the use of normal distribution and z-scores for approximation. The tutorial also explains converting discrete values to continuous for normal approximation and provides examples and applications. Finally, it outlines the criteria for using normal approximation in binomial distribution.
