Question
Assertion (A): From a bag containing 5 red balls, 2 white balls and 3 green balls, the probability of drawing a non-white ball is `4/5`.
Reason (R): For any event E, P(E) + P(not E) = 1.
Options
Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Both, Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (А).
Assertion (A) is true, but Reason (R) is false.

Solution
Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Explanation:
Assertion (A): Total number of balls = 5 (red) + 2 (white) + 3 (green) = 10
Number of non-white balls = 5 (red) + 3 (green) = 8
P(non-white) = `8/10 = 4/5`
So, Assertion (A) is true.
Reason (R): For any event E, the sum of the probability of the event and its complementary event is always 1.
`P(E) + P(barE) = 1`
So, Reason (R) is true.
