WebIn probability theory, the multinomial distribution is a generalization of the binomial distribution. For example, ... Probability mass function. Suppose one does an experiment of extracting n balls of k different colors from a bag, replacing the extracted balls after each draw. Balls of the same color are equivalent. WebDescription. y = binopdf (x,n,p) computes the binomial probability density function at each of the values in x using the corresponding number of trials in n and probability of success for each trial in p. x, n, and p can be vectors, matrices, or multidimensional arrays of the same size. Alternatively, one or more arguments can be scalars.
