Assertion (A): The probability of an event can not be 1/0.9.
Reason (R): 0 ≤ P(E) ≤ 1 for an event E.
✅ Answer & Solution
$\frac{1}{0.9}=1.11$ which is greater than 1, and since probability always satisfies $0\le P(E)\le1$, an event cannot have probability $1.11$. So Assertion is TRUE. Reason is TRUE and it correctly explains why the Assertion holds.
