An event is one or more outcomes of a probability experiment.
In an experiment of tossing a die, there are six possible outcomes.
If each face is represented by a numeral of the number of dots on the face; the following represents all of the outcomes:
{ 1, 2, 3, 4, 5, 6 }
Any of the six outcomes is an event. Note that groups of outcomes can also be an event. Some examples are given below:
Event: Getting a 1 or a 2.
Event: Getting an even number.
Event: Getting a 3.
Event: Getting a 1, 2, 3, 4, 5 or 6.
