🎲 What tool can combine multiple probability distributions across multiple variables ?

For example airline passenger weight has a somewhat normal distribution around a mean of around 78kg. Whereas carry-on bag weight is right-skewed with a mode around 6kg and a median of around 7.5kg.

What is the probability that with a B737-800 full of passengers ( say 200 passengers ) the total weigh of and carry-on bags will exceed 20,000 kg ?

At the 2026 International Lean Six Sigma Conference in Bratislava, John Dennis’s 1 hour workshop will demonstrate how 𝐌𝐨𝐧𝐭𝐞 𝐂𝐚𝐫𝐥𝐨 𝐀𝐧𝐚𝐥𝐲𝐬𝐢𝐬 can transform the way we understand risk and variation.

Using 𝐃𝐢𝐬𝐜𝐨𝐯𝐞𝐫𝐒𝐢𝐦™ by SigmaXL , participants will learn how to:

✅ Model multiple uncertain variables using appropriate probability distributions
✅ Combine those distributions into a realistic simulation of an entire system
✅ Understand the overall probability and risk profile rather than relying on simple averages
✅ Quantify the likelihood of different outcomes before making critical decisions
✅ Support better, data-driven decisions in Lean Six Sigma, Project Management, Operations and Business Strategy

𝐌𝐨𝐧𝐭𝐞 𝐂𝐚𝐫𝐥𝐨 𝐀𝐧𝐚𝐥𝐲𝐬𝐢𝐬 is a powerful extension of statistical thinking and an invaluable tool for anyone serious about managing uncertainty.
