Without replacement:\r
\n" ); document.write( "\n" ); document.write( "There are 4 purples to choose from out of the 7, so the first one has prob. 4/7.\r
\n" ); document.write( "\n" ); document.write( "Now, since the first one is not put back, there are 3 purples to choose from and 6 balls in total. So, the second has prob. 3/6=1/2\r
\n" ); document.write( "\n" ); document.write( "(4/7)(3/6)=2/7\r
\n" ); document.write( "\n" ); document.write( "
