Fundamentals of Engineering (FE) – Industrial &
Systems Exam Verified Questions, Correct
Answers, and Detailed Explanations for Science
Students||Already Graded A+
1. Which of the following best describes the role of an industrial
engineer?
A. Designing mechanical components
B. Optimizing systems involving people, materials, and information
C. Managing construction projects
D. Performing electrical circuit analysis
Answer: B
Industrial engineers focus on improving efficiency and productivity in
integrated systems.
2. A process produces 3 defects per 1,000 units. What is the defect
rate?
A. 0.003%
B. 0.03%
C. 0.3%
D. 3%
Defect rate = 3 ÷ 1000 = 0.003 = 0.3%.
3. Which probability distribution is most appropriate for modeling
the number of arrivals per hour?
A. Normal
B. Binomial
,C. Poisson
D. Exponential
Poisson distribution models discrete events occurring over time.
4. In a normal distribution, approximately what percentage of data
lies within ±1 standard deviation?
A. 68%
B. 68.3%
C. 95%
D. 99.7%
This is a key property of the empirical rule.
5. Little’s Law is expressed as:
A. WIP = Throughput × Lead Time
B. WIP = Arrival Rate × Flow Time
C. Flow Time = Capacity ÷ Demand
D. Throughput = WIP ÷ Capacity
Little’s Law applies to stable systems.
6. Which measure represents the central tendency least affected by
outliers?
A. Mean
B. Mode
C. Median
D. Range
The median is resistant to extreme values.
, 7. In linear programming, the feasible region is defined by:
A. The objective function
B. System constraints
C. Decision variables
D. Slack variables
Constraints determine the feasible solution space.
8. Which technique is used to identify the most significant causes of
a problem?
A. Flowchart
B. Control chart
C. Pareto analysis
D. Scatter diagram
Pareto analysis focuses on the “vital few.”
9. What does a control chart primarily monitor?
A. Accuracy
B. Efficiency
C. Process stability
D. Productivity
Control charts detect variation due to assignable causes.
10. If two events are independent, then:
A. P(A|B) = P(A)
B. P(A ∩ B) = P(A)P(B)
C. P(A ∪ B) = P(A) + P(B)
D. P(B|A) = P(B) + P(A)
