"The smallest showers detectable with a reasonable probability over a larger area are [tex]10^{16}[/tex] eV showers. A lower shower counting rate for the setup can be deduced by only considering showers with this energy. A [tex]10^{16}[/tex] eV -shower is detected with a probability of 0.86 at 0 m distance, 0.12 at 100 m, and with zero probability at larger distances. This can be simplified to a probability [tex]P = \frac{0.86+0.12}{2} = 0.49[/tex] to detect a shower hitting within 100 m of the center, and zero probability outside this region. This collecting area is then 31415 m[tex]^{2}[/tex]."

How did he calculate the probabilities 0.86, 0.12 and 0? Please explain, this is so important...
