ODDLY LIKELY
Everything on this site is either taken from an official source or computed here — and you can see which.
Published numbers come from the organisation that owns them: lottery odds from the operator, weather risk from the national weather service, population figures from the statistics agency. The source is linked on the page where the number appears, and the date it was checked is noted when the figure can move.
Where a number can be derived, it is — from the formula, not from another website. The birthday odds come from the exact product formula, not an approximation. The lottery calculator works from combinations. The three-doors simulator runs real random trials in your browser, so you can re-run it and watch the result wobble around two thirds.
Formulas are shown on the page. If you disagree with one, you have everything you need to check it.
No number is rounded to make a better headline. Where an assumption matters — 365 equally likely birthdays, ignoring 29 February, a US-based lifetime risk — it is stated next to the result rather than buried.
Mistakes get fixed quickly and visibly. If a figure here looks wrong, email hello@theoddlylikely.com with your working, and the page will be corrected or the reasoning explained.
The short videos are animated from the same calculations that power these pages. The narration uses a synthetic voice, which is labelled as AI on every platform that asks.
