Which is why, to reduce the 
likelihood to less than 5%
%لهذا السبب، من أجل خفض الاحتمالية إلى أقلّ من 5
Um also die Wahrscheinlichkeit
auf unter 5 % zu reduzieren,
Así que, para reducir la probabilidad
a menos del 5 %,
Así que, para reducir la probabilidad
a menos del 5 %,
Pour que la probabilité
passe à moins de 5 %,
Ecco perché, per ridurre la probabilità a meno del 5%,
Por isso, para reduzir a
probabilidade pra menos de 5%,
Поэтому, чтобы вероятность гипотезы Б 
стала менее 5%,
