stats vocab 5.1 - 5.2

Front

A number between 0 and 1 that describes the proportion of times an outcome of a chance process would occur in a very large number of repetitions.

Back

probability

Front

If we observe more and more repetitions of any chance process, the proportion of times that a specific outcome occurs approaches its probability.

Back

law of large numbers

Front

Imitation of a chance process in a way that accurately models real-world outcomes.

Back

simulation

Front

Description of some chance process that consists of two parts: a list of all possible outcomes and a probability for each outcome.

Back

probability model

Front

List of all possible outcomes of a chance process.

Back

sample space

Front

Any collection of outcomes from some chance process. Events are usually designated by capital letters, like A, B, C, and so on.

Back

event

Front

The probability that an event does not occur is 1 minus the probability that the event does occur. In symbols, P(AC) = 1 - P(A).

Back

complement rule

Front

The complement of event A, written as AC, is the event that A does not occur.

Back

complement

Front

Two events A and B that have no outcomes in common and so can never occur together. That is, P(A and B) = 0.

Back

mutually exclusive

Front

If A and B are mutually exclusive events, P(A or B) = P(A) + P(B).

Back

addition rule for mutually exclusive events
