Dembski states that, given enough time, any event with a probability larger than 10_-150 might well take place. He puts the odds of evolving the 30 proteins of the bacterial flagellum at 20_-30 ("around 10_-39")  and explains that since the flagellum requires 30 such proteins, they "will all need to be multiplied to form the origination probability", which would give an origination probability for the flagellum of 10 _-1170. This is well below the universal probability bound, demonstrating that the flagellum could not have evolved.

This is well below the universal probability bound, demonstrating, in his view, that the flagellum could not have evolved.
