You can put this solution on YOUR website!
Use 0 to represent tails and 1 to represent heads. If you flip 3 coins, the possibilities are:\r
\n" ); document.write( "\n" ); document.write( "0 0 0
\n" ); document.write( "0 0 1
\n" ); document.write( "0 1 0
\n" ); document.write( "0 1 1
\n" ); document.write( "1 0 0
\n" ); document.write( "1 0 1
\n" ); document.write( "1 1 0
\n" ); document.write( "1 1 1\r
\n" ); document.write( "\n" ); document.write( "As you can see, there are 8 total outcomes.\r
\n" ); document.write( "\n" ); document.write( "b) the chance of getting no heads would be the 0 0 0 case, which is only one of the 8 cases, so the chances are 1/8.\r
\n" ); document.write( "\n" ); document.write( "c) Exactly one head are the 001, 010, 100 cases which is 3/8.\r
\n" ); document.write( "\n" ); document.write( "d) Two heads is 011, 101, 110 which is 3/8.\r
\n" ); document.write( "\n" ); document.write( "e) Three heads is 111, which is 1/8.\r
\n" ); document.write( "\n" ); document.write( "Don't forget. Most of the time two heads are better than one.
\n" ); document.write( "
\n" );
