Question

An experiment is called random experiment if

• A. It has more than one possible outcome
• B. We are able to predict the outcome in advance
• C. It is not possible to predict the outcome in advance
• D. It has only one possible outcome

Answer 1

Answer: (A), (C)

It is not possible to predict the outcome in advance

This is the definition of a random experiment.

The two conditions a random experiment must satisfy are

1)It has more than one possible outcome.

2)It is not possible to predict the outcome in advance.

Option B says we are able to predict the outcome in advance. If we are able to predict in advance it is not random. So it is wrong

Option D says it has only one outcome. If it has only one outcome, we can predict the outcome. Again it is not random.
