coloured_formulas_2 = md`We can see that the ${tex`\colorbox{${scenario_match_colour}}{$\text{yellow area} = \lambda m$}`} and the
${tex`\colorbox{${scenario_non_match_colour}}{$\text{blue area} = (1-\lambda) u$}`}.
So:
${tex`\text{match probability} = \frac{\colorbox{${scenario_match_colour}}{{$\lambda m$}}}{\colorbox{${scenario_match_colour}}{$\lambda m$} + \colorbox{${scenario_non_match_colour}}{$(1-\lambda)u$} } `}
Which is our original formula.`
