• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

Explanation:

Assertion (A) is true: The probability of a certain or sure event is always 1, as it is guaranteed to happen.

Reason (R) is true: In any experiment, the sum of the probabilities of all possible elementary events all individual outcomes is always 1.
