CORRECT.
SECTION 1: BASIC PROBABILITY CONCEPTS
(Questions 1-10)
Q1. Which of the following values cannot be a probability?
A) 0.15
B) 1.25
C) 0.75
D) 1.00
Correct Answer: B. 1.25
Rationale: Probabilities must be between 0 and 1 inclusive (0 ≤ P ≤ 1). 1.25
is greater than 1, so it cannot be a valid probability. 0.15, 0.75, and 1.00 are
all valid probabilities.
Q2. The probability of an event that is certain to occur is:
A) 0
B) 0.5
C) 1
D) Cannot be determined
Correct Answer: C. 1
Rationale: An event that is certain to occur has a probability of 1. For
example, the probability of rolling a number between 1 and 6 on a fair die is
1.
