Stats Def

A value between zero & one, inclusive, describing the realative possibility (chance or likelyhood) an even will occur

A process that leads to the occurence of one and only one of several possible observations

A particular result of an experiment

A collection one or more outcomes of an experiment

Outcomes of an experiment are equally likely.

The occurance of one event means that none of the other events can occur at the same time

At least one of the events must occur when an experiment is conducted

The probability of an event happening is the fraction of the time similar events happened in the past

Over a large # of trials the empirical probability of an event will approach its true probability

The likelyhood (probability) of a particular event happening that is assigned by an individual based on whatever info is available.

P(A)+P(B)

1-P(~A)

P(A)+P(B)-P(A/B)

A probability that measures the likelyhood two or more events will happen concurrently.

P(A)P(B(

The occurance of one event has no effect on the probability of the occurance of another event.

P(A)P(B/A)

One out come relies on another

The probability of a particular event occuring, given that another event has occured.

A table used to classify sample observatios according to two or more identifiable characteristics.

Graph that is helpful in organizing calculations that invlove several stages

The intial probability based on the present level of information

Arevised probability based on additional information.

If there are M ways of doing one thing and n ways of doing another thing, there are MXN was of doing both

Any arrangement of r objects selected from a single group of n possible objects.
