Two statements are given, one labelled as Assertion (A) and the other is labelled as Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below :

Assertion (A): If E is an event such that $P (E) = \frac{1}{999}$ , then $P (\overline{E}) = 0.001$ .

Reason (R): $P (E) + P (\overline{E}) = 1$

(a)Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
(b)Both, Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
(c)Assertion (A) is true, but Reason (R) is false.
