\n" ); document.write( "Hi,
\n" ); document.write( "15 balls f which 4 are red, 8 are green, and 3 are blue
\n" ); document.write( "With replacement of the first ball
\n" ); document.write( "P(first ball is red and the second is green) = 4/15 * 8/15 = 32/225= .142\r
\n" ); document.write( "\n" ); document.write( "without replacement (14 total balls in the urn on the second draw)
\n" ); document.write( "P(first ball is red and the second is green) = 4/15 * 8/14 = 32/210 = .152 \n" ); document.write( "
\n" );
