In each of the Exercises choose the correct answer:If `P(A) =1/2`, `P (B) = 0`, then `P (A|B)`is(a) 0 (b) `1/2` (c) not defined (d) 1

Explanation

To solve the problem, we need to find \( P(A|B) \) given that \( P(A) = \frac{1}{2} \) and \( P(B) = 0 \).

### Step-by-Step Solution:

1. **Understand the Definition of Conditional Probability**:
The conditional probability \( P(A|B) \) is defined as:
\[
P(A|B) = \frac{P(A \cap B)}{P(B)}
