You can put this solution on YOUR website!
The tree diagram will look like the following (of course, you may have it oriented a different way)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Sample space: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "{369T,396T,639T,693T,936T,963T,369R,396R,639R,693R,936R,963R}\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 6 plates with a T in them and there are 12 plates total. So probability is 6/12 = 1/2
\n" ); document.write( "
\n" );
