• \({H_{NA}} = \frac{{{s_i}}}{{{r_i}}}\)
• \({\lambda _{KM}} = 1 – {H_{NA}}\)
• \({\rm P}[T > {\rm{ }}8|T > {\rm{ }}4] = \frac{{{\rm P}[T > {\rm{ }}8]}}{{{\rm P}[T > {\rm{ }}4]}}\)

\({\rm P}[T > {\rm{ }}8|T > {\rm{ }}4] = \frac{{{\rm P}[T > {\rm{ }}8]}}{{{\rm P}[T > {\rm{ }}4]}} = \frac{{\frac{{24}}{{25}} \times … \times \frac{7}{8}}}{{\frac{{24}}{{25}} \times … \times \frac{{17}}{{21}}}} = 0,5835\)
