Definition

Example
|
|
An experiment is a situation involving chance or
probability that leads to results called outcomes.
|
In the problem above, the experiment is spinning the
spinner.
|
|
An outcome is the result of a single trial of an
experiment.
|
The possible outcomes are landing on yellow, blue, green
or red.
|
|
An event is one or more outcomes of an
experiment.
|
One event of this experiment is landing on blue.
|
|
Probability is the measure of how likely an event is.
|
The probability of landing on blue is one fourth.
|
|
In order to measure probabilities, mathematicians have
devised the following formula for finding the probability of an event.
