Ten high-intensity bulbs are tested for 100 hours each. One failed at 40 hours; all others completed the test. Calculate FR(%) and FR(N).
High-Intensity Bulbs
Light bulbs designed to emit a very bright light, commonly used in areas requiring significant illumination.
FR(%)
A term that does not appear to match standard key terms used in inventory management, production, or finance. NO.
- Calculate Failure Rate (FR), Failure Rate Normalized (FR(N)), and Mean Time Between Failures (MTBF).

Final Answer :
FR(%) = 1/10 or 10%; operating hours = 9 × 100 + 40 = 940; FR(N) = 1/940 or 0.00106
