The first problem is:
\n" ); document.write( ":\r
\n" ); document.write( "\n" ); document.write( "since P(H)=.6 we know that P(H')=.4
\n" ); document.write( ":
\n" ); document.write( "P(G|H')=P(G and H')/P(H')
\n" ); document.write( ":
\n" ); document.write( ".25=P(G and H')/.4)---->P(G and H')=.4(.25)=.1 or 1/10
\n" ); document.write( ":
\n" ); document.write( " \n" ); document.write( "
