Question

Which of the following numbers is not the probability of any event?

• A. \(0.7\)
• B. \(2.5\)
• C. \(75%\)
• D. \(\tfrac{4}{5}\)

Hint:

Probability values must satisfy \(0 \leq P(E) \leq 1\).

Answer 1

The Correct Option is B

Step 1: Recall probability range.
Probability always lies between 0 and 1.
Step 2: Check each option.
0.7 is valid, 75% = 0.75 valid, \(\tfrac{4}{5}=0.8\) valid.
But \(2.5>1\), invalid.
