I tried that also, then however the result is #+RESULTS: #+begin_export latex \begin{align*} P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\ P(\text{No-Covid19}) &= 1- P(\text{Covid19}) = 1-0.1=0.9\\ P(\text{+}|\text{No-Covid19}) &= 1- P(\text{-}|\text{No-Covid19}) = 1-0.95=0.05 \\ &=\frac{0.95 \cdot 0.1}{0.95\cdot0.1 + (1-0.95)\cdot 0.9}\\ P(\text{Covid19}|-)&=0.608696 \\ P(\text{No-Covid19}|+)&=1-P(\text{Covid19}|+)=0.391304 \\ \end{align*} #+end_export That is ok for displaying, but if I now want also to export this org file to latex, the align construct is not exported, sigh.
