You can put this solution on YOUR website!
Sometimes it helps to list the elements of the sample space
\n" ); document.write( "so you can see the possibilities and the probabilities.
\n" ); document.write( "---
\n" ); document.write( "Use
\n" ); document.write( "(1/1)(2/2)(3/3) to indicate correctly matching all three
\n" ); document.write( "---
\n" ); document.write( "(1/1)(2/3)(3/2) is one match
\n" ); document.write( "--
\n" ); document.write( "(2/2)(1/3)(3/1) is one match
\n" ); document.write( "---
\n" ); document.write( "(3/3)(1/2)(2/1) is one match
\n" ); document.write( "---
\n" ); document.write( "If you have 2 correct matches the 3rd match must also be correct.
\n" ); document.write( "---
\n" ); document.write( "(1/2)(2/3)(3/1) is no match
\n" ); document.write( "---
\n" ); document.write( "(1/3)(2/1)(3/2) is no match
\n" ); document.write( "===============================
\n" ); document.write( "Those are the six.
\n" ); document.write( "===============================
\n" ); document.write( "Why six ?
\n" ); document.write( "You have three to match with three.
\n" ); document.write( "#1 can match with any of the 3 \"answers\".
\n" ); document.write( "#2 can match with 2 \"answers\" that remain.
\n" ); document.write( "#3 can only match with the one \"answer\" tha remains.
\n" ); document.write( "---
\n" ); document.write( "3*2*1 = 6
\n" ); document.write( "====================
