Which of the following probability cannot exist?
- 15%
- 2/3
- -0.5
- 0.01
Explanation
Step 1: Recall the definition of probability
Probability is a measure between 0 and 1, inclusive.
Step 2: Evaluate the options
15% = 0.15 (between 0 and 1)
2/3 ≈ 0.67 (between 0 and 1)
-0.5 (less than 0)
0.01 (between 0 and 1)
Step 3: Determine which option is outside the valid range
-0.5 is less than 0, which is not valid for a probability.
