You can put this solution on YOUR website!

You can use the \"multiplication principle of counting\" on this one:
\r
\n" ); document.write( "\n" ); document.write( "For each question, there is some \"possible\" number of answers.
\r
\n" ); document.write( "\n" ); document.write( "On the multiple choice questions, there are 4 possible answers.
\r
\n" ); document.write( "\n" ); document.write( "On the true/false questions, there are 2 possible answers.
\r
\n" ); document.write( "\n" ); document.write( "Now we can just multiply out all the possibilities for the 18 questions:
\r
\n" ); document.write( "\n" ); document.write( "\"4%2A4%2A4%2A4%2A4%2A4%2A4%2A4%2A4%2A4%2A2%2A2%2A2%2A2%2A2%2A2%2A2%2A2\"
\r
\n" ); document.write( "\n" ); document.write( "This can be simplified as:
\r
\n" ); document.write( "\n" ); document.write( "\"%284%5E10%29%2A%282%5E8%29\"
\r
\n" ); document.write( "\n" ); document.write( "\"1048576%2A256\"
\r
\n" ); document.write( "\n" ); document.write( "\"268435456\"
\r
\n" ); document.write( "\n" ); document.write( "There are 268,435,456 different ways in which one could answer these test questions!
\r
\n" ); document.write( "\n" ); document.write( "We could write out all the different possibilities, but it would take us years to do so. Scary, huh?
\r
\n" ); document.write( "\n" ); document.write( "I hope this helps!
\n" ); document.write( "
