Question

Define the following terms:

(i) Random experiment
(ii) Trial and out come
(iii) Sample point and sample space
(iv) Event
$\left[4\right]$

Answer 1

Random experiment: If we cannot predict the exact outcome of the experiment, such experiment is called as random experiment.
$\left[1\right]$
Trial and Outcome: Each performance of a random experiment is called a trial and the result of each trial is called an outcome.
Rolling a dice and flipping a coin are trials. Head and Tail are called outcomes.
$\left[1\right]$
Sample point and sample space: Each outcome of a random experiment is called a sample point.
The set of all possible outcomes (or Sample points) of a random experiment is called the Sample space. It is denoted by S.
$\left[1\right]$
Event: An event can be one or more than one outcome (or)
Any subset of a sample space is called an event.
