<PRE><B>Question 542356</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;You can use the &quot;multiplication principle of counting&quot; on this one:&lt;br&gt;

For each question, there is some &quot;possible&quot; number of answers.&lt;br&gt;

On the multiple choice questions, there are 4 possible answers.&lt;br&gt;

On the true/false questions, there are 2 possible answers.&lt;br&gt;

Now we can just multiply out all the possibilities for the 18 questions:&lt;br&gt;

{{{4*4*4*4*4*4*4*4*4*4*2*2*2*2*2*2*2*2}}}&lt;br&gt;

This can be simplified as:&lt;br&gt;

{{{(4^10)*(2^8)}}}&lt;br&gt;

{{{1048576*256}}}&lt;br&gt;

{{{268435456}}}&lt;br&gt;

There are 268,435,456 different ways in which one could answer these test questions!&lt;br&gt;

We could write out all the different possibilities, but it would take us years to do so.  Scary, huh?&lt;br&gt;

I hope this helps!&lt;br&gt;</PRE>
