Chapter 10 Vocabulary Flashcards
Combination
An arrangement
of items or events in which order
does not matter.
Compound event
An event
made up of two or more simple
events.
Dependent events
Events for
which the outcome of one event
affects the probability of the
second event.
Event
An outcome or set of
outcomes of an experiment or
situation.
Experiment
In probability, any
activity based on chance, such as
tossing a coin.
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.
Equally likely
Outcomes that
have the same probability.
Factorial
The product of all
whole numbers except zero that
are less than or equal to a
number.
Fair
When all outcomes of an
experiment are equally likely, the
experiment is said to be fair.
Fundamental Counting Principle
If one event has m possible outcomes and a second event has n possible outcomes after the first event has occurred, then there are m n total possible outcomes for the two events.
Independent events
Events for
which the outcome of one event
does not affect the probability of
the other.
Outcome
A possible result of a
probability experiment
Permutation
An arrangement of
items or events in which order is
important.
Complement
An arrangement
of items or events in which order
does not matter.
Probability
A number from 0 to 1
(or 0% to 100%) that describes
how likely an event is to occur.
Prediction
Something you can
reasonably expect to happen in
the future.
Sample space
All possible
outcomes of an experiment.
Simple event
An event
consisting of only one outcome.
Theoretical probability
The ratio
of the number of ways an event
can occur to the total number of
equally likely outcomes.
Trial
Each repetition or
observation of an experiment.
