the statement is:
\n" ); document.write( "if i am hungry then i will eat
\n" ); document.write( "the inverse of that statement is:
\n" ); document.write( "if i am not hungry then i will not eat.
\n" ); document.write( "the converse of that statement is:
\n" ); document.write( "if i will eat, then i am hungry.
\n" ); document.write( "the contra-positive of that statement is:
\n" ); document.write( "if i do not eat, then i am not hungry.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "we can translate those statements into logic symbols and variables.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "we let p = i am hungry
\n" ); document.write( "we let q = i will eat\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if i am hungry then i will eat translates to p->q
\n" ); document.write( "if i am not hungry then i will not eat translates to ~p->~q
\n" ); document.write( "if i eat, then i am hungry translates to q->p
\n" ); document.write( "if i don't eat, then i am not hungry translates to ~q->~p\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the general rule is:
\n" ); document.write( "p->q is the statement.
\n" ); document.write( "~p->~q is the inverse.
\n" ); document.write( "q->p is the converse.
\n" ); document.write( "~q->~p is the contra-positive.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the statement and the contra-positive are equivalent. if the statement is true, then the contra-positive is also true.
\n" ); document.write( "the inverse and the converse are equivalent. if the inverse is true, then the converse is also true.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the statement and the converse are not equivalent. sometimes the converse is true when the statement is true and sometimes it's not.
\n" ); document.write( "the statement and the inverse are not equivalent. sometimes the inverse is true when the statement is true and sometimes it's not.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the original statement is:
\n" ); document.write( "if i am hungry then i will eat
\n" ); document.write( "the statement you are asked to analyze is:
\n" ); document.write( "if i am not hungry then i will not eat.
\n" ); document.write( "that's the inverse of the statement and it is not true by the fallacy of the inverse.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
