Let’s dive into one of the trickiest topics in discrete probability distribution: the Multinomial Distribution.
Remember, when dealing with multinomial distribution, it's all about counting multiple categories across a fixed number of trials. You aren't just interested in one outcome, but multiple outcomes happening simultaneously, which makes it more dynamic and exciting!
