Is this valid? Yes: since the non-vowel letters are symmetric and do not affect relative order, and all positions are equally likely, the relative order of the three distinct vowels A, I, O is uniformly distributed over all 6 permutations. Hence, the probability they appear in alphabetical order is:

**Is This Valid? The Surprising Logic Behind A, I, O Order** Why are so many people quietly curious: *Is this valid?* Is this valid? Yes — because the non-vowel letters in any sequence are symmetric, meaning every position holds equal likelihood. Since A, I, and O are distinct vowels with no inherent order, their relative positions follow a perfectly uniform distribution across all 6 permutations. This means the probability they appear in alphabetical order — A before I before O — is a steady 1 in 6. It’s not magic — it’s probability in action. This subtle symmetry isn’t just an academic curiosity. It reveals how randomness governs patterns in language — patterns we encounter daily, often without noticing. Understanding this simple rule sheds light on broader principles of order in seemingly chaotic systems. **The Universal Order in Vowel Placement**
