COMBINATION

DEPENDENT EVENTS

A dependent event is if the occurrence of one other.

EQUALLY LIKELY

EVENT

An event is any set of one or more outcomes.

EXPERIMENT

An experiment is an activity in which results are observed

EXPERIMENT PROBABILITY

IMPOSSIBLE

can never happen an event that is impossible has a probability of 0

INDEPENDENT EVENTS

events for which the outcome of one event does not affect the probability of the other
