ecoli Posted June 17, 2010 Share Posted June 17, 2010 The book I'm reading (Probability and the Logic of Science by Jaynes) has an example in it that I'm just not following. [math] If [/math] [math] \bar{A}=AD[/math] [math] then[/math] [math] A\bar{B}=\bar{B}[/math] Which I get, but then continues to: [math] and[/math] [math] B\bar{A} = \bar{A}[/math] which I don't get, considering the boolean identities he provides. Anyone know how to do this? Link to comment Share on other sites More sharing options...
the tree Posted June 17, 2010 Share Posted June 17, 2010 It's fairly apparent that [imath]A\bar{B}=\bar{B} \implies B\bar{A}=\bar{A}[/imath] if you draw a venn diagram. edit: worth showing that AB=0 Link to comment Share on other sites More sharing options...
