there are 100C2 possible pairs of beads __ (100*99)/(2*1)=4950\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "there are 5*20 possible white-green pairs __ 5*20=100\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the probability of a white-green pair is 100/4950 or .02 (approx)
\n" ); document.write( "
\n" );
