Here's the basic outline to solving this problem\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1) Assign p: the dog licks her nose and q: the dog is happy\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2) Translate each statement into symbolic form.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3) Create a table for each symbolic statement. Any tables which have equivalent final columns will be equivalent expressions.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For example, translate \"If the dog licks her nose, then the dog is not happy. \" into p -> ~q and set up the following table\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\n" ); document.write( "\r\n" ); document.write( "\n" ); document.write( "
pq~qp -> ~q
TTFF
TFTT
FTFT
FFFT
\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Do the same for the 2 other statements and compare the last columns in the table. Let me know if this helps.
\n" ); document.write( "
\n" );
