Question
Define a trial.
✓
Answer
What is the meaning of trial?
The word trial means a test of performance, qualities, or suitability.
Definition:
Any particular performance of a random experiment is called a trial.
That is, when we perform an experiment it is called a trial of the experiment.
By experiment or trial, we mean a random experiment unless otherwise specified.
Where you are required to differentiate between a trial and an experiment, consider the experiment to be a larger entity formed by the combination of a number of trials.
To illustrate the definition, let us take examples:
$1.$ In the experiment of tossing $4$ coins, we may consider tossing each coin as a trial and therefore say that there are $4$ trials in the experiment.
$2.$ In the experiment of rolling a dice $5$ times, we may consider each rolls as a trial and therefore say that there are $5$ trials in the experiment.
Note that rolling a dice $5$ times is same as rolling $5$ dices each one time. Similarly, tossing $4$ coins is same as tossing one coin $4$ times.
