Question
Define an elementary event.
Solution
What are the meanings of elementary event?
The word elementary means simple, non decomposable into elements or other primary constituents and the word event means something that result.
Definition:
An elementary event is any single outcome of a trial. Elementary events are also called simple events.
To illustrate the definition, let us take examples:
1. In the experiment of tossing a coin, the possible outcomes H and T. Any one outcome like H is called an elementary event.
2. In the experiment of rolling a dice, the possible outcomes are 1, 2, 3, 4, 5 and 6. Any one outcome like 4 is called an elementary event.
Note that H stands for getting a head and T stands for getting a tail in the experiment of tossing a coin.
