Question

Assertion (A): If E is an event such that P(E) = `1/999`, then `P(barE)` = 0.001.

Reason (R): `P(E) + P(barE) = 1`

विकल्प

• 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 (A).

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

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

Answer 1

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

Explanation:

E is an event and P(E) = `1/999`

`P(barE)` = 0.001

We know that

`P(E) + P(barE) = 1`

`1/999 + 0.001 ≠ 1`

So, Assertion is false.

`P(E) + P(barE) = 1`

So, Reason is true.
