IASSC Certified Lean Six Sigma Black Belt (ICBB) — Question 3

A natural logarithmic base is not required for which of these distributions for probability calculations?

Answer options

• A. Weibull
• B. Binomial
• C. Poisson
• D. Normal

Correct answer: B

Explanation

The Binomial distribution does not require a natural logarithmic base for its probability calculations, as it is based on discrete outcomes. In contrast, the Weibull, Poisson, and Normal distributions often incorporate natural logarithms in their formulas for calculations involving continuous data or rates.
