Combination

An arrangement of items or events in which order doesn't matter

Compound Event

An event made up of two or more simple events

Dependent Event

Events for which the outcome of one event effects the probability of the other

Disjoint Events

when two events cannot both occur in the same trial of an experiment

Experimental probability

the ratio of the number of times an event occurs to the total number of trials, or times, that the activity is performed

Fair

When all outcomes of an experiment are equally likely. The experiment is said to be fair.

Factorial

Product of all whole numbers except 0 that are less than or equal to a number

Independent events

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

Mutually Exclusive

two events that cannot both occur in the same trial of an experiment (same as disjoint)

Outcome

a possible result of a probability experiment

Permutation

An arrangement of items or events in which order is important

Probability

A number from 0-1 that describes how likely an event is to occur

sample space

all possible outcomes of an experiment

theoretical probability

the ratio of the number of equally likely outcomes in an event to the total number of possibly outcomes

Event

Any set of 1 or more outcomes

Equally Likely

All have the same probability, x, the probabilities must add to 1.
