Question

Which of the following is an experiment?
A.Tossing a coin
B.Rolling a six-sided dice
C.Choosing a marble from a jar
D.All of the above

Answer 1

Hint: We will check for each option whether it is an experiment or not by using the concepts of probability. First, we will check that if a coin is tossed, then it’s an experiment or not? Then we will check that if a dice is rolled, is it an experiment or not? And then we will repeat the same process for choosing a marble from a jar.

Complete step-by-step answer:
An event is a set of outcomes of an experiment to which probability is assigned.
Let’s take an example, when we throw a die, the possibility of 5 appearing on the die is an event.
Before tossing a coin, we do not know the result.
When a coin is tossed, it can give any result. Either it will be a head or tail. So, this is an example of a random experiment.
If a six-sided dice will be rolled, then we do not know what is about to come. The result can be anything from 1 to 6. So, it is also an example of random experiment.
Choosing a marble from a jar is also an experiment because we are choosing one marble from the jar. And experiment is a work in which the result can be anything.
Hence, option D is the correct option.

Note: Probability is how likely something is about to happen.
When a coin is tossed, there are two possible outcomes: heads or tails.
So, the probability of an outcome is (Number of ways it can happen) \[ \div \] (Total number of outcomes)
So, when a coin is tossed, the total number of outcomes are 2.
So, the probability of occurring head is \[\dfrac{1}{2}\].
