Assertion (A) is wrong.
View all questions of this test
If the probability of an event is 0, then it is called an impossible event.
But Reason (R) is correct.
From Basic Theorem of Probability, P(B – A) = P(B) – P(A), this is true only if the condition given in the question is true.

Assertion and Reasoning
Assertion (A): The probability of an impossible event is 1.
Reasoning (R): If A is a perfect subset of B and P(A) = 0, then P(B) = 0.
Explanation
An event is impossible if its probability is 0. On the other hand, if the probability of an event is 1, then it is certain to happen. Hence, the probability of an impossible event is 0, and the probability of a certain event is 1.
Now, let us consider the reasoning given in the statement. If A is a perfect subset of B, it means that all the elements of A are also elements of B. In other words, A is a subset of B, and there are no elements in B that are not in A.
If P(A) = 0, it means that the probability of any event in A happening is 0. Since A is a subset of B, the probability of any event in B happening is at most 0 (because all events in A are also in B). Hence, the probability of B is also 0.
Therefore, we can conclude that the reasoning given in the statement is true. However, it does not provide an explanation for why the probability of an impossible event is 1. In fact, the two statements are not directly related. The assertion is a general principle of probability, while the reasoning is a specific mathematical fact about subsets.
Conclusion
In conclusion, the correct answer is option D: A is false but R is true. The probability of an impossible event is 0, not 1. However, the reasoning given in the statement is true and provides a useful fact about subsets and probabilities.
Assertion (A): The probability of an impossible event is 1.
Reasoning (R): If A is a perfect subset of B and P(A) = 0, then P(B) = 0.
Explanation
An event is impossible if its probability is 0. On the other hand, if the probability of an event is 1, then it is certain to happen. Hence, the probability of an impossible event is 0, and the probability of a certain event is 1.
Now, let us consider the reasoning given in the statement. If A is a perfect subset of B, it means that all the elements of A are also elements of B. In other words, A is a subset of B, and there are no elements in B that are not in A.
If P(A) = 0, it means that the probability of any event in A happening is 0. Since A is a subset of B, the probability of any event in B happening is at most 0 (because all events in A are also in B). Hence, the probability of B is also 0.
Therefore, we can conclude that the reasoning given in the statement is true. However, it does not provide an explanation for why the probability of an impossible event is 1. In fact, the two statements are not directly related. The assertion is a general principle of probability, while the reasoning is a specific mathematical fact about subsets.
Conclusion
In conclusion, the correct answer is option D: A is false but R is true. The probability of an impossible event is 0, not 1. However, the reasoning given in the statement is true and provides a useful fact about subsets and probabilities.
