- event
- a set of outcomes of an experiment to which a probability is assigned.
- multinomial distribution
- a generalization of the binomial distribution.
- probability
- the likelihood of an event happening. This value is always between 0 and 1.

P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes
