\n" ); document.write( "\n" ); document.write( "In this problem, we are given that the first draw is a white marble.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It means that after first draw and before the second draw there are 4 white and 4 blue marbles in the box.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, the probability to draw a white marble at the second draw is \"4%2F%284%2B4%29\" = \"4%2F8\" = \"1%2F2\" = 0.5 = 50%.       ANSWER\r
