What story and onedigit Natural Numbers explain Bayes' Theorem chart most simply?
Some students have sniveled that most examples of Bayes' Theorem use noninteger numbers. I want to try a Bayes' Theorem chart that uses just single digit Natural Numbers $\le 9$. To complete the table below most comfortably for teenagers,

what are the simplest stories?

what natural numbers ≤ 9 contrast the base rate fallacy the most? Please don't repeat a number.
The biggest number in this similar question still uses two digits, and rehashes the common example of letting D be be a disease and $H_0$ be a negative (diagnostic) test result. What other $H_0, D$ are more intuitive? Green denotes true positive and negative, red false positive and negative.
$\begin{array}{rccc} \text{Number of occurrences}&D &\lnot D &\text{Total}\\ \hline H_a &\color{green}{\Pr(D)\Pr(+D)}&\color{red}{\Pr(D^C)\Pr(+D^C)}&\text{add the 2 left entries}\\ H_0 &\color{red}{\Pr(D)\Pr(D)}&\color{green}{\Pr(D^C)\Pr(D^C)}&\text{add the 2 left entries}\\ \hline \text{Total}&\text{add the 2 above entries}&\text{add the 2 above entries}&\text{single digit integer} \end{array}$

How are you quantifying "contrast the base rate fallacy"? — Peter Taylor 27 days ago
