Solution

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

Step 2 – Reason: R is true. The probability of a sure event is 1.

Step 3 – Link: R states the probability of a sure event, but does not explain why an event with probability 0.99 is very likely.
