how likely it is that an event will occur the chance that a particular event will happen PROBABILITY

THEORETICAL PROBABLILITY The chance that an event will occur based on the numbers.

EXPERIMENTAL PROBABLILITY The chance that an event will occur based on experiments

COMPOUND PROBABLILITY The chance that more than one event will occur.

EVENTS Events can be independent or dependent.

INDEPENDENT EVENTS Events are independent if the outcome of one event does NOT change the probability of another event.

DEPENDENT EVENTS Events are dependent if the outcome of one event changes the probablity of another event.
