Let us begin by repeating the definition of a Multinomial random variable. In the multinomial experiment, we are simply fusing the events \(E_1\) and \(E_2\) into the single event "\(E_1\) or \(E_2\)". The distribution of Y = (Y1, Y2, …, Yk) is called the multinomial distribution with parameters n and p = (p1, p2, …, pk).ac. Instead of a Bernoulli trial consisting of two outcomes, each trial has K outcomes.
