Question

Which of the following is not a random experiment?
A) Rolling of an unbiased dice
B) Tossing a fair coin
C) Drawing a card from a well shuffled pack of 52 cards
D) None of these

Answer 1

Here, we are asked to find a random experiment.
The experiment whose result is unknown to us until that event happens and the outcome of it is known is called a random experiment.
Thus, check which of the given options is not a random experiment and choose the correct option.

Complete step by step solution:
Here, we are asked to find a random experiment. So, we need to understand what a random experiment exactly means.
A random experiment can be stated as “The experiment whose result is unknown to us until that event happens and the outcome of it is known”.
So, here we will check which of the given options is not a random experiment.
Option (A) is rolling of unbiased dice.
Here, until the dice is rolled and it shows up the result, we are not able to know the outcome of that. Thus, rolling of dice is a random experiment.
Option (B) is tossing a fair coin.
Here, when the coin shows the result after being tossed, then only we can tell the outcome of the event. Thus, tossing of a coin is also a random experiment.
Option (C) is drawing a card from a well shuffled pack of 52 cards.
Here, also until we take out the card, we cannot tell the outcome of the event. Thus, the drawing of a card from a pack of well shuffled cards is also a random experiment.

Thus, the required answer is not one of the given three options. So, option (D) is the correct answer.
