Question:

If $P(A)$ denotes the probability of an event $A$, then:

$P(A) < 0$
$P(A) > 1$
$0 \leq P(A) \leq 1$
$-1 \leq P(A) \leq 1$

Step-by-Step Solution

Key Concept: Range of probability for any event is $[0, 1]$.
Stepwise Solution:

The probability of any event $A$ satisfies $0 \leq P(A) \leq 1$. [1.0 Mark]

Marking Scheme:

• Stating probability range $0 \leq P(A) \leq 1$: 1.0 Mark

Correct Answer: $0 \leq P(A) \leq 1$
