34. What is the probability that three people will all randomly select the same wheel of a tricycle? ____
\n" ); document.write( "

\r\n" );
document.write( "There are three possibile ways they can all select the same wheel,\r\n" );
document.write( "\r\n" );
document.write( "1. All select the front wheel.\r\n" );
document.write( "2. All select the left rear wheel.\r\n" );
document.write( "3. All select the right rear wheel.\r\n" );
document.write( "\r\n" );
document.write( "So the numerator of the probability (the number of successful ways) is 3.\r\n" );
document.write( "\r\n" );
document.write( "There are 3 ways Tom can selecet a wheel.  For each of those 3 ways that Tom\r\n" );
document.write( "can select a wheel, there are 3 ways that Dick can select a wheel. That's\r\n" );
document.write( "3×3 or 9 ways Tom and Dick can select wheels.  For each of those 3×3 or 9 ways\r\n" );
document.write( "Tom and Dick can select wheels, there are 3 ways Harry can select a wheel,\r\n" );
document.write( "That's 3×3×3 or 9×3 or 27 ways Tom, Dick, and Harry can select wheels.\r\n" );
document.write( "\r\n" );
document.write( "Answer: 3 ways out of 27. \"Out of\" in probability means \"over\". So the answer\r\n" );
document.write( "is  which reduces to \r\n" );
