context: It is impossible that Brian is green. There is a better than even chance that Sandra got the football. It is highly unlikely that Bernhard is green. We believe that if either Bernhard is green, or Sandra got the football, then Mary picked up the apple. There is almost no chance that if Brian is green, and Sandra got the football, then Julius is a rhino. It is probably the case that if either Brian is green, or Bernhard is green, then John went to the garden.
