 Blue Bus (Tribe 1971). Mrs. Brown is run down by a bus. It is common knowledge that 80% of the buses in town are owned by Blue Bus, and the remaining 20% by Red Bus. There was no witness to the accident except Brown who is, however, color-blind. Since Blue Bus owns 80% of the buses in town, it is 80% likely that Brown was run down by a bus operated by Blue Bus, well above the 50% threshold for civil liability. Yet, merely presenting the 80% naked statistics should not be sufficient for Brown to prevail in a civil lawsuit against Blue Bus.
