Binomial, Poisson, and Multinomial Distributions
Learning Objectives
- Define multinomial outcomes
- Compute probabilities using the multinomial distribution
where
is the number of times outcome 1 occurs,
is the number of times outcome 2 occurs,
is the number of times outcome 3 occurs,
is the probability of outcome 1
For the chess example,
Note that the binomial distribution is a special case of the multinomial when .
