Term
The Law of Large Numbers
Definition
As the number of a probability experiment increases, the proportion with which a certain outcome is observed gets closer to the probability of the outcome.
Term
Probability
Definition
A measure of the likelihood of a random phenomenon or chance behavior.
Term
Experiment
Definition
Any process with uncertain results that can be repeated.
Term
Sample Space, S
Definition
The collection of all possible outcomes.
Term
Event
Definition
Any collection of outcomes from a probability experiment.
Term
Probability Model
Definition
Lists the possible outcomes of a probability experiment and each outcome's probability.
Term
Impossible Event
Definition
Occurs when the probability of the event is 0.
Term
Certainty
Definition
Occurs when the probability of the event is 1.
Term
Unusual Event
Definition
An event that has a low probability of occurring.
Term
Equally Likely Outcomes
Definition
When each outcome of an experiment has the same probability of occurring.
Term
Tree Diagram
Definition
Lists the equally likely outcomes of experiments.
Term
Subjective Probability
Definition
A subjective probability of an outcome is a probability obtained on the basis of personal judgement.
Term
Disjoint events (mutually exclusive)
Definition
Have no outcomes in common.
Term
Contingency table
Definition
relates two categories of data
Term
complement of E
Definition
all outcomes in the sample space s that are not outcomes in the event e
Term
independent event
Definition
the occurrence of event e in a probability experiment does not effect the probability of event f
Term
dependent event
Definition
the occurrence of event e in a probability experiment affects the probability of event f
Term
conditional probability
Definition
P(F|E) "the probability of even F given E) the probability that the event F occurs, given that the event E has occurred.
Term
permutation
Definition
an ordered arrangement in which r objects are chosen from n distinct (different) objects and repetition is not allowed.
Term

Definition
a collection, without regard to order, of n distinct objects without repetition.
