What’s on the Bayes' Theorem poster
The rule, 3 worked examples, and the mistake everyone makes.
- Bayes turns a prior into a posterior by weighting it with the likelihood of the obser…
- P(A | B) = P(B | A) P(A) / P(B)
- Prior P(A) = 0.01 = Posterior can stay low
- The denominator P(B) = Σ P(B | Aᵢ) P(Aᵢ)
- Odds form = Prior odds × likelihood ratio
- Common mistake: Reading the likelihood as the posterior → Weighting the likelihood by…
Posterior is proportional to likelihood times prior. The denominator only normalises, which is why the odds form is often quicker.

- Who is the Bayes' Theorem poster for?
- Bayes' Theorem belongs to the Mathematics section rather than to a school year, because math is not something one grade owns. Anyone learning probability & statistics can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Bayes' Theorem poster?
- Whenever you know P(evidence given cause) and need P(cause given evidence). A wall chart earns its place by being glanceable from where the work is happening, so Bayes' Theorem belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Bayes' Theorem?
- Central Limit Theorem, Conditional Probability and Confidence Intervals sit alongside Bayes' Theorem in the Mathematics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Central Limit TheoremConditional ProbabilityConfidence Intervals
- Is the Bayes' Theorem poster free to download and print?
- Yes. Bayes' Theorem downloads as a free PDF with no account, no email and no watermark, like everything else in the Mathematics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Bayes' Theorem poster print at?
- Bayes' Theorem is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Bayes' Theorem loses nothing.Printing guide
