Question. 16

The probability expressed as a percentage of a particular occurrence can never be

(A)

less than 100

(B)

less than 0

(C)

greater than 1

(D)

anything but a whole number

Step 1: Probability is a number that tells us how likely something is to happen.

Step 2: The lowest probability value is 0 (meaning the event is impossible).

Step 3: The highest probability value is 1 (meaning the event is certain).

Step 4: When we express probability as a percentage, we multiply it by 100.

Example:
Probability = 0 → Percentage = 0%
Probability = 1 → Percentage = 100%

Step 5: So probability (in percentage) can only range from 0% to 100%.

Step 6: It can never be less than 0% because probability cannot be negative.

Answer: (B) less than 0.
